A special election was also held on June 28, 1960, for a mid-term vacancy in North Dakota where Democrats flipped a seat to expand their majority to 66–34. As Majority Leader Lyndon Johnson was elected Vice President, Mike Mansfield became the new majority leader.

The 1864–65 United States House of Representatives elections were held on various dates in various states between June 5, 1864, and November 7, 1865, in the midst of the American Civil War and President Abraham Lincoln's reelection. Each state set its own date for its elections to the House of Representatives. Members were elected before the first session of the 39th United States Congress convened on December 4, 1865, including the at-large seat from the new state of Nevada, and the 8 from Tennessee, the first secessionist state to be readmitted. The other 10 secessionist states had not yet been readmitted, and therefore were not seated.

The 1860–61 United States House of Representatives elections were held on various dates in various states between August 6, 1860, and October 24, 1861, before or after the first session of the 37th United States Congress convened on July 4, 1861. The number of House seats initially increased to 239 when California was apportioned an extra one, but these elections were affected by the outbreak of the American Civil War and resulted in over 56 vacancies.

The 1858–59 United States House of Representatives elections were held on various dates in various states between June 7, 1858, and December 1, 1859.

The 1912–13 United States Senate elections were held on various dates in various states. They were the last U.S. Senate elections before the ratification of the Seventeenth Amendment in 1913, establishing direct elections for all Senate seats. Senators had been primarily chosen by state legislatures. Senators were elected over a wide range of time throughout 1912 and 1913, and a seat may have been filled months late or remained vacant due to legislative deadlock. Some states elected their senators directly even before passage of Seventeenth Amendment. Oregon pioneered direct election and experimented with different measures over several years until it succeeded in 1907. Soon after, Nebraska followed suit and laid the foundation for other states to adopt measures reflecting the people's will. By 1912, as many as 29 states elected senators either as nominees of their party's primary or in conjunction with a general election.

<span class="mw-page-title-main">2000 United States elections</span>

The 2000 United States elections were held on November 7, 2000. Republican governor George W. Bush of Texas defeated Democratic Vice President Al Gore of Tennessee in the presidential election. Republicans retained control of both houses of Congress, giving the party unified control of Congress and the presidency for the first time since the 1954 elections.

The 2011 United States elections were held on Tuesday, November 8. This was an off-year election, in which the only seats up for election in the United States Congress were special elections. There were also four gubernatorial races, including a special election in West Virginia. There were also state legislative elections in four states and judicial elections in three states; as well as numerous citizen initiatives, mayoral races, and a variety of other local offices on the ballot.

<span class="mw-page-title-main">2012 United States elections</span>

The 2012 United States elections took place on November 6, 2012. Democratic President Barack Obama won reelection to a second term and the Democrats gained seats in both chambers of Congress, retaining control of the Senate even though the Republican Party retained control of the House of Representatives. As of 2024, this is the most recent election cycle in which neither the presidency nor a chamber of Congress changed partisan control, and the last time that the party that won the presidency simultaneously gained seats in both the House of Representatives and the Senate.

<span class="mw-page-title-main">1996 United States elections</span>

The 1996 United States elections were held on November 5, 1996. Democratic President Bill Clinton won re-election, while the Republicans maintained their majorities in both houses of the United States Congress.

<span class="mw-page-title-main">1862–63 United States Senate elections</span>

The 1862–63 United States Senate elections were held on various dates in various states, occurring during the American Civil War. As these U.S. Senate elections were prior to the ratification of the Seventeenth Amendment in 1913, senators were chosen by state legislatures. Senators were elected over a wide range of time throughout 1862 and 1863, and a seat may have been filled months late or remained vacant due to legislative deadlock. In these elections, terms were up for the senators in Class 1.

The 2018 United States Senate elections were held on November 6, 2018. Among the 100 seats, the 33 of Class 1 were contested in regular elections while 2 others were contested in special elections due to Senate vacancies in Minnesota and Mississippi. The regular election winners were elected to 6-year terms running from January 3, 2019, to January 3, 2025. Senate Democrats had 26 seats up for election, while Senate Republicans had 9 seats up for election.

<span class="mw-page-title-main">2017 United States elections</span>

The 2017 United States elections were held, in large part, on Tuesday, November 7, 2017. This off-year election featured gubernatorial elections in Virginia and New Jersey, as well as state legislative elections in both houses of the New Jersey Legislature and in the Virginia House of Delegates. Numerous citizen initiatives, mayoral races, and a variety of other local elections also occurred. Special elections were also held for one seat of the U.S. Senate, representing Alabama, and six seats of the U.S. House of Representatives. The Democrats picked up the governorship in New Jersey and the Alabama Senate seat that was up for a special election. The governorship in Virginia and the six House seats that were up for special elections did not change party hands.

The 2024 United States House of Representatives elections were held on November 5, 2024, as part of the 2024 United States elections, to elect the 441 members of the House of Representatives - representatives from all 435 congressional districts across each of the 50 U.S. states, as well as 6 non-voting delegates from the District of Columbia and the inhabited U.S. territories to the United States House of Representatives. Special elections have also been held on various dates in 2024. Numerous other federal, state, and local elections, including the U.S. presidential election and elections to the Senate, were also held on this date. The winners of this election will serve in the 119th United States Congress, with seats apportioned among the states based on the 2020 United States census.
