Former President Donald Trump (R) won the November 5, 2024, presidential election.

The Democratic Party selected Vice President Kamala Harris (D) as its nominee during a virtual roll call vote on August 2, 2024, ahead of the in-person 2024 Democratic National Convention, which took place from August 19-22, 2024, in Chicago, Illinois.[1][2][3][4][5]

The Republican Party selected former President Donald Trump (R) as its 2024 presidential nominee at the 2024 Republican National Convention, which was held from July 15-18, 2024, in Milwaukee, Wisconsin.

Twenty-four candidates appeared on presidential election ballots across the country. Of those candidates, four qualified to appear on enough ballots — totaling at least 270 electoral votes — to win a majority of the Electoral College. Those noteworthy presidential candidates were Kamala Harris (D), Donald Trump (R), Jill Stein (G), and Chase Oliver (L).

Featured analysis (from 2022)

  • Congressional margin of victory analysis: An electoral margin of victory (MOV) is the difference between the share of votes cast for the winning candidate and the runner-up in a single-seat election. In a multi-seat race, the MOV is the difference between the vote share received by the bottom-placing winning candidate and the top-placing losing candidate. Margins of victory can be used to measure electoral competitiveness, political party or candidate strength, and, indirectly, the popularity of a particular policy or set of policies. Congressional races in 2022, on average, were decided by a similar margin of victory (MOV) as in 2020. Relative to 2020, the average MOV increased in the Senate and in the House.
  • Rematches in 2024 general elections: An election rematch occurs when the same candidates run against each other in consecutive election cycles. In the 2024 general election, 536 elections in Ballotpedia's coverage scope were rematches for single-seat offices between the same candidates who ran in 2022. Additionally, 69 elections in 2024 were rematches for single-seat offices between the same candidates who ran in 2020.[8]

Republicans won control of the U.S. Senate, winning a 53-45 majority with two independents as a result of the November 5, 2024 elections. Two independents—Sens. Angus King and Bernie Sanders—caucus with the Democratic Party.

As a result of the elections, Republicans gained four seats in Montana, Ohio, Pennsylvania, and West Virginia. Democrats gained one seat in Arizona. This was a net change of +4 Republicans, -2 Democrats, and -2 independents.

Heading into the 2024 general election, Democrats had a 47-49 majority with four independents. Three of those independents caucused with the Democratic Party, and one other, Sen. Kyrsten Sinema counted towards the Democratic majority for committee purposes.

Thirty-four of 100 Senate seats were up for election. Thirty-three of those seats were up for regular election, and one[9] was up for a special election. Democrats were defending three Senate seats, in Montana, Ohio, and West Virginia, in states Donald Trump (R) won in the 2020 presidential election. Republicans were not defending any Senate seats in states Joe Biden (D) won in 2020.

Of the seats up for election in 2024, Democrats held 19, Republicans held 11, and independents held four. Eight members of the U.S. Senate did not run for re-election, more than in any year since 2012.

Ballotpedia identified 15 races (41.2%) as general election battlegrounds in 2024. Heading into the elections, Democrats held 11 of those seats, Republicans held three, and independents held one. Republicans won three seats previously held by Democrats in Montana, Ohio, and Pennsylvania and Democrats won the seat in Arizona, previously held by Kyrsten Sinema (I).

Ten seats were open because the incumbent did not run for re-election. Nine incumbents retired from public office and one incumbent ran for another office. Click here to learn more.

Ballotpedia does not include incumbents leaving office early in our analysis of incumbents not running for re-election. For more information about incumbents who left office early or announced resignations, click here.

Two special elections also took place on Nov. 5, 2024. One special election was held to fill the last two years of the six-year term that Sen. Ben Sasse (R-Neb.) was elected to in 2020.[10] The other special election was held to fill the rest of the six-year term that Dianne Feinstein (D-Calif.) was elected to in 2018. Feinstein died on Sept. 29, 2023. The Senate seat Feinstein held was also up for regular election on Nov. 5, 2024.[11] Ballotpedia identified 15 races as general election battlegrounds in 2024.

These battleground races were selected using the following criteria. For more information on our methodology, click here:

  • the results of the 2020 presidential election in each state,
  • whether the incumbent was seeking re-election,
  • whether the incumbent was serving his or her first term in the U.S. Senate, and
  • how the Cook Political Report, Sabato's Crystal Ball, and Inside Elections with Nathan Gonzales rated the race.

Heading into the election, Democrats held a 50-49 majority in the U.S. Senate heading into the elections.[12] As a result of the elections, Republicans gained a 53-47 majority.[13]

  • Annual State Legislative Competitiveness Report: Vol. 12, 2022: Competitiveness refers to the presence of choice throughout the election cycle. A greater level of competitiveness means voters have the ability to make more decisions. A lower level of competitiveness equals fewer choices. State legislative competitiveness in 2022 reached its highest level compared to all even-year election cycles since 2010. In 2022, the nationwide State Legislative Competitiveness Index is 36.2, beating out 2018 (36.1) and the 2012 post-redistricting cycle (35.2).

State executive elections

State-capitol-utah.jpg
See also: State executive official elections, 2024

State executive offices up for election in 2024 included 11 gubernatorial seats, nine lieutenant gubernatorial seats, 10 attorney general seats, and seven secretary of state seats. Including down-ballot races, there were 167 state executive seats up for election across 30 states in 2024.[15]

In 2022, 307 state executive offices were up for election across 44 states. Twenty offices changed party control, including two previously held Republican lieutenant governorships that changed parties because the governor and lieutenant governor ran on a joint ticket. Of the 18 offices which changed partisan control due to direct election, 10 switched from Democrat to Republican, seven switched from Republican to Democrat, and one nonpartisan official was succeeded by a Republican. A total of 26 incumbents seeking re-election to state executive offices were defeated, with 10 of those losing in the general election and 16 losing in their party's primary or nominating convention.

Featured analysis (from 2022)

  • Trifecta vulnerability in the 2022 elections: Thirteen state government trifectas were vulnerable in the 2022 elections, according to Ballotpedia's annual trifecta vulnerability ratings. Democrats defended seven vulnerable trifectas and Republicans defended six. A state government trifecta occurs when one party holds the governorship and majorities in both chambers of the state legislature. At the time of the 2022 elections, there were 37 state government trifectas: 23 Republican trifectas and 14 Democratic trifectas. The remaining 13 states had a divided government where neither party had a trifecta.
  • State government triplexes: Heading into the November 8 elections, there were 23 Republican triplexes, 18 Democratic triplexes, and 9 divided governments where neither party held triplex control. A state government triplex is a term to describe when one political party holds the following three positions in a state's government: governor, attorney general, and secretary of state.[16] In states where the attorney general or secretary of state are appointed by the governor, Ballotpedia considers the office to be held by the governor's party for the purposes of defining triplexes.[17]
  • Annual State Executive Competitiveness Report: Ballotpedia's 2022 study of competitiveness in state executive official elections found that 37.1% of incumbents did not seek re-election, leaving those offices open. This was higher than in 2020 (35.6%) and 2014 (32.7%) but lower than in 2018 (38.6%) and 2016 (45.2%). The decade average for open offices was 37.8%.

  • Partisanship in United States municipal elections (2023): Twenty-nine of the 100 largest cities held mayoral elections in 2023. Heading into the year, 20 of those cities had a Democratic mayor, seven had a Republican mayor, one mayor was independent, and one mayor's partisan affiliation was unknown. Mayoral offices changed partisan control in five cities in 2023—four as the result of elections and one party switch—resulting in no net change in the number of offices held by Democrats and a net loss of two Republican-held offices. Libertarians and independents gained one office each. Once mayors elected in 2023 assumed office, Democrats held 63 top-100 mayoral offices, Republicans held 26, Libertarians held one, independents held four, and nonpartisan mayors held four.

Down-ballot state executive offices that exist in all 50 states include superintendent of schools, insurance commissioner, agriculture commissioner, labor commissioner, and public service commissioner. Examples of other down-ballot state executive offices include treasurer, auditor, and comptroller.
