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, LDI: -1), Mary Lightbody (HD 19, LDI: 3), Beth Liston (HD 21, LDI: 6), Allison Russo (HD 24, LDI: 4), Jessica Miranda (HD 28, LDI: 0), and Casey Weinstein (HD 37, LDI: -1). Democrats lost HD 59 (LDI: -7).

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) 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.

Updated LDI scores incorporating the 2018 election results will be released in spring 2019.
