The most recent polling data from February 2025 puts the approval rating of the United States Congress at 29 percent, reflecting a significant increase from January. The approval rating remained low throughout the 118th Congress cycle, which began in January 2025. Congressional approval Congressional approval, particularly over the past few years, has not been high. Americans tend to see Congress as a group of ineffectual politicians who are out of touch with their constituents. The 118th Congress began in 2023 with a rocky start. The Democratic Party maintains control of the Senate, but Republicans took back control of the House of Representatives after the 2022 midterm elections. The House caught media attention from its first days with a contentious fight for the position of Speaker of the House. Representative Kevin McCarthy was eventually sworn in as Speaker after a historic fifteen rounds of voting. Despite the current Congress having a historic share of women and being the most diverse Congress in American history, very little has been done to improve the opinion of Americans regarding its central lawmaking body. Ye of little faith However, Americans tend not to have much confidence in many of the institutions in the United States. Additionally, public confidence in the ability of the Republican and Democratic parties to work together has decreased drastically between 2008 and 2022, with nearly 60 percent of Americans having no confidence the parties can govern in a bipartisan way.

Since 1789, 45 different men have served as President of the United States, and the average age of these men when taking office for the first time was approximately 57 years. Two men, Grover Cleveland and Donald Trump, were elected to two non-consecutive terms, and Donald Trump's victory in 2024 made him the oldest man ever elected as president, where he will be 78 years and seven months old when taking office again. Record holders The oldest president to take office for the first time was Joe Biden in 2021, at 78 years and two months - around five months younger than Donald Trump when he assumes office in 2025. The youngest presidents to take office were Theodore Roosevelt in 1901 (42 years and 322 days), who assumed office following the assassination of William McKinley, and the youngest elected president was John F Kennedy in 1961 (43 years and 236 days). Historically, there seems to be little correlation between age and electability, and the past five presidents have included the two oldest to ever take office, and two of the youngest. Requirements to become president The United States Constitution states that both the President and Vice President must be at least 35 years old when taking office, and must have lived in the United States for at least 14 years of their life. Such restrictions are also in place for members of the U.S. Congress, although the age and residency barriers are lower. Additionally, for the roles of President and Vice President, there is a "natural-born-citizen" clause that was traditionally interpreted to mean candidates must have been born in the U.S. (or were citizens when the Constitution was adopted). However, the clause's ambiguity has led to something of a reinterpretation in the past decades, with most now interpreting it as also applying to those eligible for birthright citizenship, as some recent candidates were born overseas.

45 men have served as the President of the United States. Of these 45 men, 31 have had a military background, with ranks ranging from a militia private to five-star generals. There is some correlation between the ages of the presidents and major wars in U.S. history; explaining why none of those in office between 1909 and 1945 had any military background, and why six of the ten veteran presidents since then served in the National Guard or Naval Reserve. Three US presidents have held the highest position in the U.S. military, they were; George Washington, Commander in Chief of the Continental Army during the War of Independence; Ulysses S. Grant, Commanding General of the US Army during the American Civil War; and Dwight D. Eisenhower, Supreme Commander of the Allied Expeditionary Force in Europe in the Second World War. Popular professions In terms of non-military roles, the most common profession for U.S. presidents before taking office was that of a lawyer. 27 U.S. presidents studied and practiced law before entering the world of politics, while Harry S. Truman met all the criteria to become a lawyer, before political and personal circumstances prevented this (although he was posthumously awarded an honorary law license in 1996). Joe Biden is the most recent U.S. president to have held this job; however, the profession was most common in earlier years, as 22 of the first 32 presidents had been lawyers. Eight presidents had also worked in the education sector, with four schoolteachers, three college professors and one university dean being elected to office, and a number went on to teach or serve on university boards after their time in office. More uncommon jobs for U.S. presidents include Hollywood actor (Ronald Reagan), inventor (Thomas Jefferson), peanut farmer (Jimmy Carter) and reality TV host (Donald Trump). Donald Trump was the only U.S. President without any military or political background before assuming office. Political roles A total of 15 vice presidents have ascended to the presidency; eight were due to the death of their respective president, six were elected for their first term, and Gerald R. Ford assumed the presidency following the resignation of Richard Nixon. Of the nine men who assumed the presidency following a death or resignation, five were re-elected to serve a full term. Thomas Jefferson and Richard Nixon are the only vice presidents to have won two presidential elections, and Jefferson is the only one to have completed both full terms. The most common political background of a U.S. president is that of a Congressman in the House of Representatives, with 18 presidents having served in this role, while 17 also served in the U.S. Congress as Senators. Additionally, 17 U.S. presidents had served as state governors, and William Howard Taft was the Governor-General of the Philippines from 1901 to 1903, when it was a U.S. territory. Six U.S. Presidents had previously served as Secretaries of State, while Taft and Grant had served as Secretaries of War, and Herbert Hoover had been the Secretary of Commerce.
