The 10 Senate seats most likely to flip in 2026

Key Points:

• The Senate battleground map has expanded to 10 competitive seats, now including Kansas, where Democrats have not won a Senate seat in 94 years, signaling improved prospects for Democrats in red-leaning states like Ohio, Alaska, and Texas.
• Democrats need to gain four Republican-held seats while defending three of their own, with key races in North Carolina, Ohio, Alaska, Maine, Texas, Michigan, Iowa, New Hampshire, Kansas, and Georgia shaping the battle for Senate control.
• Despite Trump’s low approval rating at 34% amid economic frustrations and the Iran war, Republicans are poised to outspend Democrats in advertising for most competitive Senate races, though Democrats have seen surging enthusiasm and early voting turnout.
• Notable races include North Carolina where Democrat Roy Cooper leads significantly, Ohio where former Sen. Sherrod Brown is competitive against GOP Sen. Jon Husted, and Alaska where Democrat Mary Peltola holds a lead in a complex ranked-choice race against GOP Sen. Dan Sullivan.
• Other key contests include Texas with Democrat James Talarico challenging Attorney General Ken Paxton amid scandals, Michigan’s tight race between Abdul El-Sayed and Mike Rogers, and Kansas emerging as a new battleground with Democrat Adam Hamilton tied with GOP Sen. Roger Marshall.
