Special elections that changed partisan control

New York's 3rd Congressional District

See also: New York's 3rd Congressional District special election, 2024

Tom Suozzi (D) defeated Mazi Pilip (R) in a special election in New York's 3rd Congressional District on February 13, 2024. The election was called following the expulsion of George Santos (R).

Suozzi represented an earlier version of the district from 2017 to 2023 and was a candidate for governor in the 2022 Democratic primary, while Pilip had served in the Nassau County Legislature since 2021. Because this was a special election, leaders in the Queens and Nassau county parties selected both candidates rather than holding primaries.[5][6][7]

Local political analysts said that support for Israel was likely to be an issue in the race, with both Suozzi and Pilip saying they were strong supporters of the country. Hofstra University professor Lawrence Levy said the issue could affect turnout for Suozzi: "There’s not an inch of daylight between Suozzi and Pilip on support for Israel...but the Democratic Party is seeing younger voters at odds with Israel."[8] In an interview with Politico, Suozzi said Democrats who opposed U.S. aid to Israel were not informed on the issue: "They don’t understand what a serious threat this is to not only Israel and Jews throughout the world, but to America and our allies. They’re just not educated about the issues."[9]

The outcome of the election helped to determine the balance of members in the U.S. House of Representatives. At the time of the election, Republicans had 219 seats to Democrats' 212, a seven-seat margin for Republicans. Suozzi's win expanded the Democratic minority, bringing the partisan balance to a six-seat margin of 219-213. A win for Pilip would have expanded the Republican majority to an eight-seat margin of 220-212.

Suozzi will serve the remainder of Santos' term, which ends on January 3, 2025. Candidates for the special election were still eligible to run in the regular 2024 election.

In the 2022 election, Santos defeated Robert Zimmerman (D) 53.7%-46.2%. This was the first election after the 2020 round of redistricting, which analysts assessed shifted the district towards Republicans.

The U.S. House voted to expel Santos on December 1, 2023.[10]

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.[59]

Elections to the U.S. Senate were held on November 5, 2024, and 34 of the 100 seats were up for election. Thirty-three of those seats are up for regular election, and one[60] was up for a special election.

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 counted towards the Democratic majority for committee purposes.

Thirty-four of 100 seats were up for election, including one special election. Of the 34 seats up for election in 2024, Democrats held 19, Republicans held 11, and independents held four. Democrats were defending three Senate seats 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.

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.[61] 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.[62]

In 2024, 10 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.

Ballotpedia is tracking 15 races (41.2%) as battleground races. Democrats held 11 of those seats, Republicans held three, and an independent held one.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.

Following the 2022 elections, Democrats gained a net of one seat, maintaining control of the chamber. Republicans held 49 seats following the elections, while Democrats held 49 seats and independents who caucus with Democrats held two. After the elections, Sen. Kyrsten Sinema announced she had changed her party affiliation from Democrat to Independent. Sinema kept the committee assignments she had as a member of the Democratic caucus.[63]

Heading into the 2024 elections, the partisan breakdown in the U.S. Senate is as follows:

Partisan composition, U.S. Senate
