In the Senate midterm elections, Democrats hope to win at least two new seats to regain control of the chamber, but their margin for error is slim. A majority of the seats up for election in 2018 are currently held by Democrats.
In the House midterm elections, Democrats need to flip 24 seats to capture the 218 seats necessary for control of the chamber. There are 182 solidly Democratic seats and 161 solidly Republican seats. The competitive races below are listed by state and district number.
In addition to congressional elections, there are also 36 governor’s races on the ballot in 2018. With the next redistricting process set for after the 2020 election, winning gubernatorial and state legislative control will be crucial for both parties.
