2020 Update

Republicans currently control the Ohio State House 61-38. Democrats need to flip 12 seats to take control of the chamber.

In 2020, all State House districts will be on the ballot. EveryDistrict has identified two districts that lean Democratic, one district that leans Republican, and six districts that favor Republicans that Democrats can compete in to grow their caucus in the legislature.

With the right investment, Democrats can grow their numbers in the Ohio legislature. To learn how you can get involved to support state legislative candidates on the ballot in Ohio in 2020, sign up for EveryDistrict’s email list.

2018 Election Update

After the 2016 election, Republicans controlled the Ohio State House 66-33. In the 2018 election, Democrats flipped six Republican-held seats and lost one Democratic-held seat for a net gain of five seats. Republicans now control the chamber 61-38.

EveryDistrict endorsed all six of the successful Democratic challengers: Phil Robinson (HD 6), Mary Lightbody (HD 19), Beth Liston (HD 21), Allison Russo (HD 24), Jessica Miranda (HD 28), and Casey Weinstein (HD 37). Democrats lost HD 59.

EveryDistrict identified ten other districts as competitive and endorsed candidates in four of those districts: Russ Harris (HD 23), Dan Foley (HD 43), Joe Helle (HD 89), and Taylor Sappington (HD 94).

Understanding the Map

EveryDistrict’s Legislative District Index (LDI) is the gold standard of state legislative competitiveness. Our LDI ranks state legislative districts on a scale from 100 to -100, using statewide elections data. Districts with a score of 100 would vote for statewide Democratic candidates by an average of 100 points (with the Democratic candidate receiving 100% of the vote); districts with a score of -100 would vote for statewide Republican candidates by an average of 100 points (with the Republican candidate receiving 100% of the vote). For a more realistic example, a district with a score of 10 would vote for statewide Democratic candidates by an average of 10 points (meaning we would expect the Democratic state legislative candidate to win with 55% of the vote compared to the Republican winning 45% of the vote).

EveryDistrict divides winnable districts into five categories. Dark blue districts lean Democratic and are held by a Democratic legislator. Light blue districts lean Republican and are held by a Democratic legislator. Yellow districts lean Democratic but are held by a Republican legislator; these districts represent the best pick up opportunities for Democrats. Pink districts lean slightly Republican, with a range of 0 up to -5; in the current political climate we’ve identified these districts as pick up opportunities for Democrats. Dark red districts are held by a Republican and have an LDI score of less than -5.

After the 2018 election, EveryDistrict reviewed and enhanced our LDI system, improving the accuracy of the metric with new methodologies and the most recent electoral data.
