Which states have Senate races in 2020?

As the election approaches, here is a quick overview of the states with Senate races this election year. Each state has two senators, elected for six-year terms. Those terms are staggered so that around one-third of all senators are up for reelection every two years, and normally no more than one Senate seat is on the ballot per state. This year, because of a special election in Georgia — where there is also a regular Senate race scheduled — there will be 35 races in 34 states on election day.

There are 20 Republican incumbents and 11 Democratic incumbents defending their seats this fall. Four Senators are not seeking reelection — three Republicans and one Democrat.
