About one-third of the Senators in Congress are elected every two years. This means the 33 are up for election at any one time.
Thirty-three of the 100 Senate seats are up for reelection. The Republicans will be defending just 8 seats, while the Democrats will be fighting for 23, plus another 2 held by independents. The winners of those seats will serve a six-year term from January 3, 2019, until January 3, 2025.
