Ballotpedia identifies 2018 battleground legislative chambers

Fifteen state legislative chambers may see shifts in party control in 2018

Middleton, Wis. – Ballotpedia has identified 15 state legislative battleground chambers in 2018. Heading into the 2018 elections, Democrats control nine battleground chambers and Republicans control six.

Battlegrounds are chambers that are expected to be more competitive than other chambers and have the potential to see significant shifts in party control. Some could even see the majority party lose power. Ballotpedia uses criteria such as the majority party’s share of seats and the number of competitive races to determine if a chamber will be a battleground.

The 2018 elections are occurring in the aftermath of significant Republican gains in state legislative elections from 2010 to 2016. Heading into the 2018 elections, Republicans control 32 of the country’s 50 state legislatures, Democrats control 13, and five legislatures are split between the parties.
