Every 10 years, the number of seats a state has in the U.S. House of Representatives, and therefore the Electoral College, changes based on population. While many states experienced no change in representation due to the 2020 Census, a few states gained or lost seats. Texas notably gained *** seats due to an increase in population, while New York, Michigan, California, West Virginia, Pennsylvania, Ohio, and Illinois all lost *** seat.

This change will stay in place until 2030, when the next Census is conducted in the United States.

There are 435 seats in the U.S. House of Representatives, of which 52 are allocated to the state of California. Seats in the House are allocated based on the population of each state. To ensure proportional and dynamic representation, congressional apportionment is reevaluated every 10 years based on census population data. After the 2020 census, six states gained a seat - Colorado, Florida, Montana, North Carolina, and Oregon. The states of California, Illinois, Michigan, New York, Ohio, Pennsylvania, and West Virginia lost a seat.

Over one week after the election, the Republicans had won *** seats in the United States House of Representatives during the 2024 election, securing their majority. As of November 25, three seats remained uncalled. Parties need to earn *** seats in the House of Representatives in order to claim a majority.

I examine whether indirect and direct elections lead to the selection of different types of legislators. My research design, which compares senators to representatives who were elected from statewide districts, takes advantage of two unique features of the nineteenth century congressional districting process. First, some states elected their entire congressional delegation in at-large districts. Second, many states that gained a seat during reapportionment would elect the new representative in a statewide contest rather than redrawing district lines. As a result, there are not only more representatives elected statewide, but they also come from a more diverse set of states than in contemporary elections. Overall, I find that indirectly elected legislators were more comparable to directly elected legislators on some dimensions than prior studies suggest.

Inspiration

What are the states that are most vulnerable to switch from Republican to Democrat control or from Democrat to Republican control?

Legislative super majorities are defined as being 66% greater than or equal to the number of seats held by the Republican party or the Democratic party. What are the states that are close to being a Republican or Democratic super majority?

Also, what is the least costly state to turn from Republican to Democrat or from Democrat to Republican?

The TIGER/Line shapefiles and related database files (.dbf) are an extract of selected geographic and cartographic information from the U.S. Census Bureau's Master Address File / Topologically Integrated Geographic Encoding and Referencing (MAF/TIGER) Database (MTDB). The MTDB represents a seamless national file with no overlaps or gaps between parts, however, each TIGER/Line shapefile is designed to stand alone as an independent data set, or they can be combined to cover the entire nation. Congressional Districts are the 435 areas from which people are elected to the U.S. House of Representatives. After the apportionment of congressional seats among the States based on census population counts, each State is responsible for establishing congressional districts for the purpose of electing representatives. Each congressional district is to be as equal in population to all other congressional districts in a State as practicable. The 116th Congress is seated from January 2019 to 2021. The TIGER/Line shapefiles for the District of Columbia, Puerto Rico, and the Island Areas (American Samoa, Guam, the Commonwealth of the Northern Mariana Islands, and the U.S. Virgin Islands) each contain a single record for the non-voting delegate district in these areas. The boundaries of all other congressional districts reflect information provided to the Census Bureau by the states by May 1, 2018

Notes Definitions of variables : Uncontested seats: the number of seats in which only one candidate ran for office, and won the seat without any votes having to be cast. The database shows the number of voters enrolled in uncontested seats. Although there have been very few uncontested seats at general elections in Australia since 1980, they were a regular feature of elections in some states until the 1960s. The frequency of uncontested seats and the number of enrolled voters they contain can be a useful indicator of the competitiveness of the party system at a general election. For more information and analysis, see Campbell Sharman, 'Uncontested Seats and the Evolution of Party Competition: The Australian Case', Party Politics, 9(6) November 2003: 679-702. ballots Ballots are the papers on which votes are recorded. A vote can be a single mark, or one or more marks or numbers to elect one or more candidates. At some elections, voters could mark ballots with more than one vote, giving the result that there were more votes cast than voters. This was the case for elections for the South Australian House of Assembly until 1927. Turnout - The turnout at at election is the proportion of voters on the electoral roll (registered voters) who cast a vote. In this database, turnout is measured as the rate of voting in contested seats, shown as a percentage of registered voters; see also compulsory voting. Electoral district - Electoral districts are also called electorates but, as the term electorate also refers to the whole body of voters across a political system, the term electoral district has been used in this database to keep the distinction clear; Electoral roll - The electoral roll is the list of voters who are registered to vote at an election. compulsory preferences - a requirement that a voter must rank all candidates on the ballot paper under a system of preferential voting. Electoral system - The electoral system is the set of rules which specifies how elections are organized and how votes are cast and counted at an election. The broad category of electoral system used to elect members at an election is shown in the database, and the entries are indexed in this database under the name of each electoral system. Australia has been adventurous in its experimentation with electoral rules and electoral law. It is planned to add more information on Australian electoral rules to the database. first past the post - A first past the post electoral system is one in which a voter is required to mark the ballot paper, usually with a cross or tick, indicating the voter's preferred candidate. The winning candidate is the one with the most votes. In electoral contests where there are only two candidates, the candidate with the most votes will have a majority (that is, more than 50 percent of the votes cast). If there are more than two candidates, the candidate with the most votes may only have a plurality (that is, more than any other candidate, but less that 50 percent of the votes cast). For this reason, first past the post voting is sometimes called plurality voting and is indicated in this database as 'first past the post (plurality) voting'. First past the post electoral systems were widely used in Australia until the rise of the Australian Labor Party prompted anti-Labor parties after 1910 to adopt preferential voting for most lower house elections in Australia. First past the post electoral systems are usually associated with single member districts, but they can also be used in multimember districts. The use of plurality voting with multimember districts is often called 'block voting'; the voter is given as many votes as there are candidates to be elected from the district. Such a system favours well organized party tickets and a successful party can win all the seats in a multimember district with a plurality of votes. This system was used for the Commonwealth Senate until 1919. Plurality voting can also be used in multimember districts by giving the voters as many ballots as there are candidates to be elected from the district. This enables voters to vote for several candidates or to cast more than one ballot for their favoured candidate (see also ballots). first preference vote - Preferential voting requires a voter to rank candidates on the ballot paper in the order of the voter's choice. A voter's most preferred candidate is the one against whose name the voter has written '1' on the ballot paper. This candidate represents the voter's first preference vote. This definition also applies to voting under systems of proportional representation. Where a first past the post (plurality) electoral system is used, the first preference vote refers to the number of ticks or crosses gained by each candidate. Change from previous election (Swing) The change in first preference vote won by a party at a given election when compared with the previous election, expressed as the difference between the percentage first preference vote shares. Note that the party must be listed in the database for both elections (see listed party) for a figure to appear in the column. If the party was a listed party in the previous election but ran candidates under a difference name, no figure for changed vote share will appear (see party name). Turnout - The turnout at at election is the proportion of voters on the electoral roll (registered voters) who cast a vote. In this database, turnout is measured as the rate of voting in contested seats, shown as a percentage of registered voters. Registration of voters - Registration (enrolment) as a voter is now compulsory for all Australian parliamentary elections (note the partial exception of South Australia, below). With minor qualifications for length of residence and variations for some state and territory elections, all eligible Australian citizens are required to be registered as voters. Comprehensive voter registration can be achieved by surveying households, and by requiring state agencies which compile lists of names and addresses to provided these lists to electoral authorities. For commentary on the context of compulsory registration, see David M Farrell and Ian McAllister, The Australian Electoral System: Origins, Variations and Consequences, pp 121-124 (Sydney: University of New South Wales Press, 2006, ISBN 0868408581). History Compulsory enrolment was introduced for Victorian lower house elections in 1930. Election dates for the Tasmanian elections are: 20 April 1892, 20 September 1894, 14 October 1897, 1 November 1900, 1 October 1902, 1 June 1904, 14 April 1907, 29 December 1908, 16 November 1911, 26 November 1914, 15 November 1917, 21 October 1920, 30 August 1921, 26 June 1924, 9 April 1927, 30 November 1929, 14 May 1932, 2 March 1935, 2 October 1937, 15 March 1940, 12 June 1943, 10 November 1945, 8 November 1947, 13 May 1950, 5 December 1952, 28 May 1955, 31 May 1958, 15 July 1961, 27 June 1964, 29 April 1967, 30 May 1970, 19 May 1973, 20 March 1976, 5 May 1979, 3 April 1982, 2 March 1985, 1 October 1988, 3 October 1992, 30 March 1996, 18 September 1999, 30 November 2002, 25 November 2006.

Since 1852, the U.S. presidential election has been contested in California 44 times, with Californians successfully voting for the winning candidate on 35 occasions, giving an overall success rate of 80 percent. California has awarded the majority of its electoral votes to the Republican Party in 23 elections, the Democratic Party in 20 elections, and the only year when a third-party candidate won a majority was in 1912, where Theodore Roosevelt won the state while campaigning as the Progressive Party's nominee. Between 1952 and 1988, there was only one election that was not won by the Republican candidate, while all elections since 1992 have been won by the Democratic nominee. In the 2024 election, Oakland-born Vice President Kamala Harris ran as the Democratic nominee, and comfortably won her home state but lost the nationwide vote. Californian under-representation? California was admitted to the union in 1850, and was granted just four electoral votes in its first three presidential elections. In the past two centuries, California's population has grown rapidly, largely due to a positive net migration rate from within the U.S. and abroad. Today, it has the highest population of any state in the U.S, with almost forty million people, and has therefore been designated 54 electoral votes; the most of any state. Although California has been allocated around ten percent of the total electoral votes on offer nationwide, The Golden State is home to roughly twelve percent of the total U.S. population, therefore a number closer to 62 electoral votes would be more proportional to the U.S. population distribution. Despite this, California's total allocation was reduced to 54 in the 2024 election. Native Californians As of 2020, Richard Nixon is the only native Californian to have been elected to the presidency, having won the election in 1968 and 1972. California also voted for Nixon in the 1960 election, although John F. Kennedy was the overall winner. Two other U.S. Presidents had declared California as their home state; they were Herbert Hoover, who won the 1928 election, and Ronald Reagan, who won in 1980 and 1984 respectively. While states generally support candidates who were born or reside there, Californian candidates have failed to carry their home state or state of birth in four U.S. presidential elections, these were; John C. Frémont in 1854 (who actually came third in California), Herbert Hoover in 1932, and Adlai Stevenson in both the 1952 and 1956 elections.

This statistic shows the results for the United States House of Representatives in the 2018 midterm election. During that election, 234 seats were won by Democratic candidates, compared to 201 Republican wins.

There are 435 voting members of the House of Representatives, and six non-voting members. 218 seats are needed for control of the House. Members of the House of Representatives have a two year term, which means that every two years, each seat is up for election. In the 2018 midterm elections, Democrats won control of the House of Representatives for the upcoming 116th United States Congress, which will convene on January 3, 2019.

AbstractThe Parliament consists of the King (represented by the Governor-General) and two Houses (the Senate and the House of Representatives).The House of Representatives reviews, debates and votes on proposed laws.Each member elected to the House of Representatives represents a single electoral division, also known as an electorate, which does not cross state or territory borders.Each of the six states, the Australian Capital Territory and Northern Territory gains representation in the House of Representatives in proportion to their population, and there are a similar number of electors in each electoral division within a given state or territory.The names and boundaries of electoral divisions within a state or territory are reviewed periodically and may be adjusted.This process is known as a redistribution of federal electoral divisions.The Federal Electoral Divisions dataset contains the names and geographic boundaries of the federal electoral divisions in Australia.The Senate is also often referred to as the ‘state’s house’ or the ‘house of review’.The Senate"s law-making powers are equal to those of the House of Representatives except that it cannot introduce or amend proposed laws that authorise expenditure for the ordinary annual services of the government or that impose taxation.Those elected to the Senate are called ‘Senator’.Senators represent all of one of the six states, the Australian Capital Territory or the Northern Territory.There are 12 senators for each of the six states and there are two senators each for the Australian Capital Territory and the Northern Territory.These boundaries are provided in vector format with Electoral Divisions represented by polygons.Redistributions of federal electoral divisions are conducted of individual states or territories. The electoral divisions in this data have been used at general elections conducted since the date on which the redistribution was determined:NSW - electoral divisions reflect changes made as a result of the redistribution of New South Wales determined on 10 October 2024.VIC - electoral divisions reflect changes made as a result of the redistribution of Victoria determined on 17 October 2024.QLD - electoral divisions reflect changes made as a result of the redistribution of Queensland determined on 27 March 2018.WA - electoral divisions reflect changes made as a result of the redistribution of Western Australia determined on 24 September 2024.SA - electoral divisions reflect changes made as a result of the redistribution of South Australia determined on 20 July 2018.TAS - electoral divisions reflect changes made as a result of the redistribution of Tasmania determined on 14 November 2017.ACT - electoral divisions reflect changes made as a result of the redistribution of the Australian Capital Territory determined on 13 July 2018.NT - electoral divisions reflect changes made as a result of the redistribution of the Northern Territory determined on 4 March 2025.CurrencyDate modified: 4 March 2025Data extentSpatial extentNorth: -9.115517°South: -43.740510°East: 167.998035°West: 96.816941°Source InformationThe data is downloadable from the AEC website.Further information can be found on the AEC's GIS page.Catalog entry: Product catalogue.Known LimitationsThe data (Federal Electoral Divisions 2025) has been used in Digital Atlas of Australia with the permission of the Australian Electoral Commission.

All 435 seats in the United States House of Representatives were up for election in the 2022 midterms. The day before the election, nine of those seats were considered toss-up seats – meaning they could reasonably be won by either party this election cycle. To have a majority in the House, one party must occupy 218 of the 435 seats. Many of the toss-up seats in this election cycle were located in California, New York, Ohio, and Pennsylvania.

This statistic displays the seats won in the provincial elections for the States-Provincial in the Netherlands in March 2019. Prime Minister Mark Rutte's liberal VVD (People's Party for Freedom and Democracy) lost its status as the largest party in the States-Provincial, winning 80 seats. With 86 seats new Forum voor Democratie (Forum for Democracy) became the largest party in the States-Provincial. In comparison to the House of Representatives and the Senate there are relatively many parties represented in the States-Provincial that only operate on the provincial level.

According to results on November 6, 2024, former President Donald Trump had received *** Electoral College votes in the race to become the next President of the United States, securing him the presidency. With all states counted, Trump received a total of *** electoral votes. Candidates need *** votes to become the next President of the United States.

As of December, 2022, Donald Trump endorsed 172 candidates for the midterm United States House of Representatives in primary and general elections taking place across the United States. 147 of the endorsed candidates won their general election to take-up a seat in the House. The former presidents endorsements included Marjorie Taylor Green of Georgia, Jim Jordan of Ohio, and Kevin McCarthy of California.

Republican candidate Kelly Daughtry was the top fundraiser leading up to primary elections in North Carolinas’ **** congressional district. Daughtry is the only candidate to raise over ************* dollars. The top Democratic fundraiser was Wiley Nickel, who won the Democratic primary, raising nearly *** million dollars. Republican Robert Hines raised *** million dollars and won the Republican primary for the seat in the House of Representatives. Hines will face off with Wiley Nickel in the midterm general election scheduled for November *** 2022.In American politics, a battleground or swing state is any state that could reasonably be won by either Democratic or Republican party by a swing in votes from one party to the other.

Republican incumbent candidate Yvette Herrell raised over four million dollars during her campaign for the House of Representatives seat for New Mexico’s second district. Democratic candidate Gabriel Vasquez raised just over three million dollars and Darshan Patel raised just over 67,000 dollars. Vasquez won the general election for the House seat, flipping it to Democratic control. In American politics, a battleground or swing state is any state that could reasonably be won by either Democratic or Republican party by a swing in votes from one party to the other.

California's **** district is classified as a battleground state in the upcoming midterm elections due to its current Republican representative serving in the U.S. House of Representatives, yet the district voted majoritarily for Democratic presidential candidate Joe Biden in the last U.S. presidential election. Republican incumbent candidate Michelle Steel was the top fundraiser leading up to primary elections in California's highly contested **** congressional district, raising over ************ U.S dollars. Jay Chen was the highest fundraising Democratic candidate, bringing in *********** U.S. dollars. Michelle Steel and Jay Chen will face one another in the midterm general election scheduled for ****************.In American politics, a battleground, toss-up or swing state is any state that could reasonably be won by either Democratic or Republican party by a swing in votes from one party to the other.
