12 key races that will determine who controls the Senate

As the 2026 primary season concludes, the stage is set for the fall midterm elections, which will determine control of the Senate. Republicans currently hold a 53-seat majority, but the political landscape is shifting due to an unpopular war with Iran and ongoing affordability issues, making several GOP-held seats vulnerable. Democrats need to gain four seats to secure a majority. Key races include Maine, where GOP Sen. Susan Collins faces Democrat Troy Jackson, and Michigan, where Democrat Abdul El-Sayed is up against former GOP Rep. Mike Rogers. Collins, known for her independent stance, faces a tough challenge from Jackson, a working-class advocate. Meanwhile, El-Sayed, a former health official, emerged from a contentious primary to challenge Rogers. These races are crucial as they could tip the balance of power in the Senate.
