Home / Government / Articles / 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.
