The 2026 U.S. Senate races are already shaping up to be highly competitive, with several key states set to feature tight contests. Here are the seven most anticipated races:
- Maine
Sen. Susan Collins (R-Maine) has long been a target for Democrats in this Democratic-leaning state. Although she has managed to fend off challenges, her bid for a sixth term in 2026 may be closely watched, particularly given her moderate stance. Democrats will need a strong candidate, possibly from their 2020 nominee pool, but Collins remains a formidable opponent. - North Carolina
After narrowly losing to Sen. Thom Tillis (R-N.C.) in 2020, Democrats are hopeful for another chance, especially with the potential entry of popular outgoing Gov. Roy Cooper. If Cooper runs, it could dramatically change the dynamics of this race, although Tillis’ strength and lack of a divisive primary may make him a tough opponent. - Georgia
The Georgia Senate race, which helped decide control of the Senate in 2020, will again be a battleground. Incumbent Sen. Jon Ossoff (D-Ga.) could face a strong challenge, especially with potential Republican contenders like Rep. Buddy Carter and Governor Brian Kemp, who is nearing the end of his second term. - Michigan
Sen. Gary Peters (D-Mich.) is a strong incumbent, but the GOP is eyeing Michigan as a potential flip, especially after near-upsets in past races. Although no major Republican challenger has yet emerged, the party will be looking for a strong contender to challenge Peters in this competitive state. - Ohio
Ohio’s Senate race is particularly interesting with an open seat following JD Vance’s exit to become Vice President-elect. Republicans are expected to field a strong candidate, such as state Sen. Matt Dolan or Secretary of State Frank LaRose. Democrats may also see this as a chance, especially if former Sen. Sherrod Brown makes a comeback bid. - New Hampshire
Sen. Jeanne Shaheen (D-N.H.) has maintained a solid grip on her seat, but New Hampshire remains a potential target for Republicans. The most formidable GOP contender would be popular outgoing Gov. Chris Sununu, though he has shown little interest in running. Former Sen. Scott Brown could also make a return to challenge Shaheen. - Texas
Although Democrats have been eyeing Texas for a blue flip since 2018, they have fallen short in each attempt. Incumbent Sen. John Cornyn (R-Texas) may face a challenge, especially if a controversial Republican candidate like Attorney General Ken Paxton enters the race. Despite this, Texas remains a potential battleground in the 2026 election cycle.
These states will play a pivotal role in determining Senate control, with candidates from both parties gearing up for a fierce campaign season.
