U.S. Senate Elections 2024

Democratic Control of the Senate is On The Line

Thirty-four U.S. Senate seats will be decided in the coming November 5 election. The Senate currently has 51 Democrats (including the 3 Independents) and 49 Republicans. With Joe Manchin (D) retiring, the Republicans almost certainly will pick up a seat in West Virginia. The margin for Democrats to maintain control of the Senate could not be slimmer.

It may come down to the election results in 9 states. Michigan, Pennsylvania, Nevada, and Wisconsin have Democratic Senators and are considered “leaning Democratic.” Montana, Ohio, and Arizona also have Democratic Senators, but they are considered “toss-ups.” Texas and Florida have Republican Senators and are considered “leaning Republican,” but Democrats may have a shot.

This listing of U.S. Senate races includes race ratings from The Cook Political Report. The ratings indicate if one party is perceived to have an advantage and, if so, the degree of advantage, according to the following definitions:

Primaries

The thirty-four states conduct their primaries for the November 5 elections beginning on March 5, 2024, and ending on September 10, 2024. The remaining primaries are:
