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.
