U.S. Senate Seats up for Reelection in 2020

It's 2020 vision time. The U.S. Senate elections will be held on November 3, 2020. Thirty-four of the 100 Senate seats are up for reelection. The GOP will have to defend more Senate seats than Democrats. As of now, there will be 22 Republican Senate seats on the line, while Democrats will only need to protect 12 seats. The time to start organizing is now.
