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 six-year terms beginning with the 118th United States Congress. Two special elections were held to complete unexpired terms. While pundits considered the Republican Party a slight favorite to gain control of the Senate, Senate Democrats outperformed expectations and expanded the majority they had held since 2021,^[2][3] gaining one seat for a functioning 51–49 majority.

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

While Republicans were slightly favored in several competitive races, a red wave election did not materialize.^[6][7][8] Democrats gained one 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]

Partisan composition[edit]

All 34 Class 3 senators were up for election in 2022; prior to 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 two 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 three 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 one 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]

Final pre-election predictions[edit]

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

Race summary[edit]

Special elections during the preceding Congress[edit]

In each special election, the winner's term can begin immediately after their election is certified by their state's government. In cases where a resignation has been previously announced, the new senator's term can begin once the previous senator's resignation is submitted officially.

Incumbent four-term Democratic Party Senator Chuck Schumer, who had served as Senate Majority Leader since 2021 and had held New York's Class 3 Senate seat since defeating Republican Party incumbent Al D'Amato in 1998, ran for a fifth term. Republican Party challenger Joe Pinion was the first black Senate nominee of any major party in New York history. The filing deadline for the June primary was April 7, 2022.^[135] Schumer became the longest-serving U.S. senator in the state's history once his fifth term began.^[136]

Pinion flipped the more conservative counties that Schumer had won in his previous runs, as well as some Democratic leaning counties such as Nassau, Saratoga, Broome, Clinton, and Essex. However, Schumer's lead was large enough in New York City that it was called by most media outlets the moment the polls closed.^[137]
