US Senate Midterms 2026: Key Races That Could Flip Control

The 2026 US Senate midterm elections are shaping up to be a competitive battle as Democrats seek to overturn Republicans' 53-47 majority. With Election Day approaching, several closely contested races could determine which party controls the chamber.

Democrats must defend vulnerable seats while flipping Republican-held states, including at least two that President Donald Trump won by double-digit margins in 2024.

In Georgia, Democratic Senator Jon Ossoff holds a double-digit polling advantage over Republican Mike Collins. Ossoff has raised $98 million, significantly exceeding Collins' $7.4 million, strengthening his reelection prospects.

Michigan presents another critical challenge. Progressive Democrat Abdul El-Sayed faces Republican Mike Rogers in a competitive race. Polls show El-Sayed ahead by 1 to 7 points, despite Republicans spending $86 million compared with Democrats' $41 million.

In New Hampshire, Democratic Representative Chris Pappas leads former Republican Senator John Sununu by 5 to 8 points. However, Republican spending has exceeded Democratic expenditures.

Maine offers Democrats a major pickup opportunity. Republican Senator Susan Collins faces former state Senate President Troy Jackson, who leads recent surveys by 4 points despite substantial Republican campaign spending.

North Carolina could also shift Democratic. Former Governor Roy Cooper maintains a polling advantage over Republican Michael Whatley, although Republicans have invested heavily in the contest.

Ohio remains a crucial battleground, with former Democratic Senator Sherrod Brown challenging Republican Senator Jon Husted. Outside spending has surpassed $200 million, making it one of the country's costliest Senate races.

In Alaska, Democrat Mary Peltola is polling competitively against Republican incumbent Dan Sullivan. The state's ranked-choice voting system adds uncertainty to the outcome.

Iowa features Republican Ashley Hinson against Democrat Josh Turek, with both candidates showing narrow polling leads amid concerns over tariffs and the Iran war.

Texas has emerged as another potential Democratic opportunity. Democrat James Talarico faces Republican Attorney General Ken Paxton, with recent surveys showing a tie or Talarico leading by up to 6 points.

Kansas has unexpectedly become competitive, with Democrat Adam Hamilton polling ahead of Republican Senator Roger Marshall by 1 to 5 points.

With fundraising, political spending and voter sentiment reshaping the electoral landscape, the 2026 Senate electionscould deliver significant changes to Washington's balance of power.
