Senators are divided into three classes whose terms are staggered, so that a different class is elected every two years. Class 2 senators were last elected in 2020 and are up for election in 2026. With the election of John Thune as leader of the Republican Conference, this will be the first election year since 2006 in which Senate Republicans are not led by Mitch McConnell. The Senate Democratic Conference has been led by Chuck Schumer since 2017.
Special elections have been scheduled in Ohio and Florida, following the resignation of JD Vance to become vice president and Marco Rubio's resignation to become United States secretary of state.
Two incumbent senators—Bill Cassidy of Louisiana and John Cornyn of Texas—lost renomination in their respective primaries. The last incumbent senator to lose renomination was Richard Lugar in 2012,[e] and the last time multiple elected incumbent senators lost renomination in primaries was in 2010.[f] The last incumbent senator to place no better than third in a primary before Cassidy was Hattie Caraway in 1944.[1][g]
Two nominees—Graham Platner and Lindsey Graham—were replaced, respectively by a convention and a special primary, as their party's nominee in Maine and South Carolina. The last nominee to be replaced by a convention or special primary was John Walsh in 2014.[h] The last time multiple nominees were replaced was in 2002, with Robert Torricelli of New Jersey and Paul Wellstone of Minnesota.
Partisan composition
All 33 Class 2 Senate seats and two Class 3 seats are up for election in 2026. Class 2 currently consists of 20 Republicans and 13 Democrats.[2] Democrats are defending two seats in states won by Donald Trump in 2024, in both cases by less than 3 percentage points: Michigan, where incumbent Gary Peters is not running for reelection; and Georgia, where the incumbent is Jon Ossoff. Michigan elected Democrat Elissa Slotkin to the Senate in 2024 by 0.3 percentage points. Georgia did not have a Senate election in 2024, although in the most recent Senate election, in 2022, Democrat Raphael Warnock won by three points in a runoff.[3][4]
Five incumbent Democratic senators represent states won by Kamala Harris by single-digit margins in 2024: New Hampshire's Jeanne Shaheen, Minnesota's Tina Smith, Virginia's Mark Warner, New Jersey's Cory Booker, and New Mexico's Ben Ray Luján.[3] Shaheen and Smith are not running for reelection.[5] Susan Collins's seat in Maine is the only seat being defended by a Republican in a state that Kamala Harris won in 2024.[6] Republican Thom Tillis of North Carolina is retiring[7] from the Senate in a state that Trump won by a single-digit margin in 2024.[3]
The 2026 Senate map is considered favorable to Republicans, even though Democrats are defending 13 seats and Republicans 22. Most rating groups identify two Republican-held seats as highly competitive and three or four others as somewhat competitive. By contrast, Democrats must flip at least four seats to win a majority while defending two highly vulnerable seats and two others viewed as somewhat vulnerable.[8][9][10] Pollsters have found Democrats' chances to flip the Senate to be improving due to nominees in states such as North Carolina, Ohio, and Alaska running highly competitive campaigns.[11] But Democrats' odds of flipping the Senate may have diminished after controversy over their nominees in Maine and Michigan.[12]
Change in composition
Each block represents one of the one hundred seats in the U.S. Senate. "D#" is a Democratic senator, "I#" is an Independent senator, and "R#" is a Republican senator. They are arranged so that the parties are separated and a majority is clear by crossing the middle.

Predictions
Multiple sites and political pundits have published predictions of competitive seats. These predictions have considered factors such as the strength of the incumbent (if the incumbent was running for reelection) and the other candidates, and the state's partisan lean, reflected in part by the state's Cook Partisan Voting Index rating. The predictions typically assign ratings to each seat, indicating the predicted advantage that a party had in winning that seat. Most election predictors use:
- "tossup": no advantage
- "tilt" (used by some predictors): advantage that is not quite as strong as "lean"
- "lean": slight advantage
- "likely": significant, but surmountable, advantage
- "safe" or "solid": near-certain chance of victory

Potentially competitive seats
These are seats that polling and predictions currently have listed as at least somewhat close.
Republican incumbents
One Republican-held senate seat, North Carolina, is considered competitive but favoring the Democrats.[47] Former Governor Roy Cooper overwhelmingly won the Democratic nomination for the open seat.[48] Incumbent Republican senator Thom Tillis is retiring,[23] with former Republican National Committee Chairman Michael Whatley becoming the Republican nominee, endorsed by Donald Trump.[49]
Five Republican-held Senate races are expected to be highly competitive: Maine, Ohio, Alaska, Texas, and Iowa. Incumbent Susan Collins is seeking reelection in Maine;[50] it is regarded as competitive due to the state's blue lean, but Collins previously kept her seat during cycles favorable to Democrats nationally (2008 and 2020). Military veteran Graham Platner was the Democratic nominee in Maine until he withdrew from the race due to allegations of sexual assault. He was replaced by former Maine Senate president Troy Jackson.[51][52] Incumbents in Ohio (Jon Husted) and Alaska (Dan Sullivan) are expected to have competitive races against former U.S. senator Sherrod Brown and former U.S. representative Mary Peltola, respectively.[50] Both Brown and Peltola lost reelection in 2024. In Texas, incumbent Senator John Cornyn lost the Texas Senate Republican primary election to Texas Attorney General Ken Paxton, who is expected to have a competitive race against State Representative James Talarico. In Iowa, the incumbent Joni Ernst is not seeking reelection;[17] the race to succeed Ernst between Republican U.S. representative Ashley Hinson and Democratic state representative Josh Turek is expected to be competitive.
Six other Republican-held Senate races are expected to favor Republicans but are viewed as somewhat competitive by some predictors: Nebraska, Kansas, Florida, Montana, South Carolina, and Louisiana. In Nebraska, incumbent Senator Pete Ricketts is challenged by independent Dan Osborn, who ran against Republican Deb Fischer in the Class I race in 2024. Osborn was the most successful challenger of a Republican-held seat during the 2024 election cycle, losing by only six points, compared to Kamala Harris's loss by 20 points in Nebraska in the concurrent presidential election. In August 2025, the Nebraska Democratic Party endorsed Osborn.[53] Louisiana is expected to heavily favor Republicans; incumbent Senator Bill Cassidy was challenged by Louisiana State Treasurer John Fleming and U.S. representative Julia Letlow, with Letlow winning the primary election, marking the first time an elected incumbent senator had lost their primary in any state since 2012 in Indiana.[e]
Democratic incumbents
The Democratic-held Senate race expected to be the most competitive is in Michigan, where senator Gary Peters has announced his retirement. The state has an even PVI score.[54][50] Former US Representative for the 8th congressional district and 2024 U.S. Senate nominee Mike Rogers[55] is the Republican nominee. Former Wayne County Health, Human, and Veterans Services Department Director Abdul El-Sayed[56] is the Democratic nominee.
In Georgia, incumbent Democratic senator Jon Ossoff is running against Republican Mike Collins, the U.S. representative from Georgia's 10th congressional district.[57] It was initially expected to be a very competitive race,[50] but election predictors have become increasingly confident of Ossoff's prospects.[58]
The seats in Minnesota (vacated by Tina Smith), and New Hampshire (vacated by Jeanne Shaheen) are also expected to be only marginally close races. In New Hampshire, popular former Republican governor Chris Sununu declined to run;[31][59] his brother, former Senator John E. Sununu, announced a run for the Senate seat he lost to Shaheen in 2008.[60] Some polls have showed John E. Sununu in a dead heat with Chris Pappas, the Democratic front-runner.[61][62] Former U.S. Senator from Massachusetts and U.S. Ambassador to New Zealand and Samoa Scott Brown has announced his candidacy. Brown was the Republican nominee in 2014, narrowly losing the general election to Shaheen.[63]
