The 2022 United States Senate elections were held on November 8, 2022, concurrently with other midterm elections at the federal, state, and local levels. Regularly scheduled elections were held for 34 of the 100 seats in the U.S. Senate, the winners of which will serve 6-year terms beginning with the 118th United States Congress. 2 special elections were held to complete unexpired terms. While pundits considered the Republican Party a slight favorite to gain control of the Senate, the Democrats outperformed expectations and expanded the majority they had held since 2021,^[2][3] gaining a seat for a functioning 51–49 majority.

Senators are divided into 3 classes whose terms are staggered so that a different class is elected every other year. All 34 Class 3 Senate seats, last elected in 2016, were up for election in 2022. Before the elections, Class 3 consisted of 14 Democrats and 20 Republicans. Special elections were concurrently held in California, to fill Vice President Kamala Harris's unexpired Senate term ending in 2022,^[4] and in Oklahoma, to fill the remaining 4 years of Jim Inhofe's unexpired term.^[5] 5 Republican senators and 1 Democratic senator retired instead of seeking re-election; 15 Republicans and 13 Democrats ran for re-election. Before the elections, Democrats had held a majority in the Senate since January 20, 2021. There were 48 Democratic and 2 Independent senators who caucused with them; Harris's tie-breaking vote as vice president gave Democrats control of the chamber.^[2]

While Republicans appeared slightly favored in several competitive races, a red wave election did not materialize.^[6][7][8] Democrats gained a seat, in Pennsylvania where Democrat John Fetterman won the election to succeed retiring Republican Pat Toomey.^[9] All incumbents won re-election, and all other open seats besides Pennsylvania were held by the same party as the retiring senator. For the first time since the ratification of the 17th Amendment, no incumbent lost a U.S. Senate primary or general election.^[10][f]

The better-than-expected performance of Democrats has been attributed to several factors,^[11] including the issue of abortion after Dobbs v. Jackson Women's Health Organization,^[12] the role of Donald Trump, and alleged extremism or election denialism among Republicans.^[13][14][15] The 2022 election cycle was the first time in U.S. history in which multiple Senate races in the same year were contested between two Black nominees (Georgia and South Carolina).^[16][g]

All 34 Class 3 senators were up for election in 2022; before Election Day, Class 3 consisted of 14 Democrats and 20 Republicans, including a seat in California held by an interim appointee up for a special election. Additionally, a special election was held for a Class 2 seat in Oklahoma. Of the senators not up for election, 34 were Democrats, 29 were Republicans, and 2 were Independents who caucused with the Senate Democrats.^[2]

In recent cycles, partisanship in Senate elections has much more closely matched partisanship in presidential elections, and the number of senators representing states won recently by presidential candidates of the opposite party has dwindled. In 2018, Democrats were defending 10 seats in states that Donald Trump won in the 2016 U.S. presidential election,^[h] while Republicans held only one seat in a state that Hillary Clinton won in 2016 (Nevada, which Democrats flipped). In contrast, Democrats in this cycle held no seats in states that Trump won in the 2020 U.S. presidential election, while Republicans were defending only two seats in states Joe Biden won in 2020 (Pennsylvania, which Democrats flipped, and Wisconsin, which Republicans narrowly held).^[2]

Democrats had held a majority in the Senate since January 20, 2021, following the party's twin victories in the run-offs for Georgia's regular and special 2020–2021 Senate elections, and the inauguration of Harris as vice president. While many pundits believed Republicans had a strong chance to flip control of the chamber, a red wave election did not materialize.^[6][7][8] Instead, Democrats performed better than expected in many states, including Pennsylvania, New Hampshire, and Ohio.^[2][17][18] In Colorado, where some Republican strategists hoped for a competitive race, Michael Bennet won re-election handily, and in New Hampshire, another hopeful Republican target, Maggie Hassan ran ahead of Biden's 2020 margin in the state.^[17][18] Democrats also beat expectations in Rust Belt states; although Tim Ryan lost in Ohio, his performance in the race had a coattail effect that boosted Democrats in competitive House districts in the state,^[19] and in Pennsylvania, where John Fetterman defeated Trump-endorsee Mehmet Oz, vulnerable House Democrats also benefitted from strong Democratic performance at the top of the ticket.^[20] Fetterman improved upon Biden's 2020 results from white voters without a college degree.^[21] In Georgia's first round, Raphael Warnock improved upon his margin from 2020–2021 and finished first,^[2] before winning by 3 percentage points in the December runoff.^[22]

Democrats' strong performance has been attributed to, among other factors,^[11] backlash to abortion-rights restrictions following the U.S. Supreme Court's June 2022 decision in Dobbs v. Jackson Women's Health Organization that overturned Roe v. Wade,^[12] negative reaction to Republican extremism and election denialism,^[14][15] better candidate quality among Democrats than Republicans,^[13] and youth turnout and vote splitting in key races.^[23][24] Some Republicans blamed Trump for the party's underwhelming showing, citing the underperformance of candidates he endorsed such as Herschel Walker in Georgia and Oz in Pennsylvania.^[25][26][27] Democrats won full terms in the Class 3 Senate seats in Arizona and Pennsylvania for the first time since the 1962 elections.

The 2022 election cycle was the first time since the 2006 Senate elections that Democrats made net gains in a midterm year, and the 2022 cycle tied with the 1990 elections for the lowest number of party flips, at only 1 seat each. This was only the third election in U.S. history (after 1914 and 1934) where the opposition party failed to flip any Senate seats. It is the most recent election cycle in which the president's party gained Senate seats and simultaneously lost House seats in a midterm, which also occurred in 1914, 1962, 1970, and 2018; it was the first midterm in which Democrats did so since 1962.^[28] It was a historically good cycle for incumbents;^[29] it was the first time ever since the ratification of the 17th Amendment, which mandated the popular election of U.S. senators, in which no incumbents were defeated for either a primary or general election.^[10][f] Maggie Hassan (New Hampshire), Ron Johnson (Wisconsin), Mark Kelly (Arizona), Catherine Cortez-Masto (Nevada), Lisa Murkowski (Alaska), and Warnock (Georgia) faced competitive races but were all re-elected.^[2][3]

Key:	D# Democratic R# Republican I# Independent, caucusing with Democrats

Several sites and individuals publish predictions of competitive seats. These predictions look at factors such as the strength of the incumbent (if the incumbent is running for re-election) and the other candidates and the state's partisan lean (reflected in part by the state's Cook Partisan Voting Index rating). The predictions assign ratings to each seat, indicating the predicted advantage that a party had in winning that seat. Most election predictors use:

• "tossup" / "battleground": no advantage
• "tilt" (used by some predictors): minimal, smallest advantage
• "lean": slight advantage
• "likely": significant, but surmountable, advantage
• "safe" or "solid": near-certain chance of victory

One Democrat and five Republicans retired instead of seeking re-election.

U.S. senator before election Lisa Murkowski Republican Elected U.S. senator Lisa Murkowski Republican

Three-term Republican Lisa Murkowski was re-elected in 2016 with 44.4% of the vote. Alaska voters passed a ballot initiative in 2020 that adopted a new top-four ranked-choice voting system: all candidates compete in a nonpartisan blanket primary, the top four candidates advance to the general election, and the winner is determined by instant-runoff voting using ranked-choice ballots. On March 30, following the Alaska Republican Party's decision to censure senator Murkowski, former Alaska Department of Administration commissioner Kelly Tshibaka announced her campaign against Murkowski, later receiving Donald Trump's endorsement.^[73] Republican governor Mike Dunleavy, who was considered another potential challenger to Murkowski, instead ran for re-election.^[74]

Murkowski, Tshibaka, Republican Buzz Kelley, and Democrat Pat Chesbro advanced to the general election.^[75] Kelley suspended his campaign in September and endorsed Tshibaka, although his name remained on the ballot.^[76]

Murkowski received a slight plurality of the first-choice votes and a majority of all votes following the ranked choice tabulation, winning re-election to a fourth full term.^[57]

U.S. senator before election Raphael Warnock Democratic Elected U.S. Senator Raphael Warnock Democratic

Incumbent Democrat Raphael Warnock won the 2020–2021 special election against incumbent Republican Kelly Loeffler to fill the remainder of former senator Johnny Isakson's term. Isakson resigned at the end of 2019 due to health problems, and Loeffler was appointed by Governor Brian Kemp following Isakson's resignation. No candidate in the open election on November 3 received the 50% required by Georgia law to avoid a run-off, a type of election colloquially known as a "jungle primary"^[110]—Warnock received just 32.9% of the vote—and so, a run-off election between Warnock and Loeffler was held on January 5, 2021, which Warnock won with 51% of the vote.

Former Republican senator David Perdue, who narrowly lost his race to Democratic challenger Jon Ossoff in 2021,^[111] and former U.S. representative Doug Collins^[112] both considered challenging Warnock, but eventually announced they were not running.^[113]

Former NFL player Herschel Walker,^[114] who had been endorsed by former president Donald Trump,^[115] defeated banking executive Latham Saddler^[116] and others in the Republican primary.

In the general election, no candidate received a majority of the vote.^[117] Warnock defeated Walker in a runoff between the top-two finishers on December 6.^[118]
