The 2026 Senate elections

How the 2026 Senate map works

Senators serve staggered six-year terms, so roughly a third of the chamber is elected every two years. The 2026 cycle covers Class 2, which leans heavily toward the South and the Mountain West, and both parties are defending seats they cannot afford to lose. Special elections in Florida and Ohio add two contests outside the regular rotation, each filling the remainder of an unexpired term.
