In 2018, we supported a citizen-led, bipartisan ballot initiative to reform the redistricting process for Ohio’s congressional districts. In May 2018, 75% of Ohio voters backed the reform measure to make the redistricting process less partisan in 2021. In November 2018, we helped Democrats flip seats in the Ohio state House. Despite these victories, Ohio remains a deeply gerrymandered swing state and is currently under trifecta control by Republicans. As such, Ohio will remain an NDRC target in 2020 — we are targeting the state House.



Redistricting in Ohio

The following timeline is a high-level overview outlining major redistricting events and activity in the state of Ohio over the last 10 years.


Republicans won trifecta control of the state, meaning that Republicans controlled the governorship and both chambers of the state legislature.


Census data delivered to Ohio.

Republican-controlled legislature drew the congressional map.

Republican Governor John Kasich signed maps into law.

Politician-led redistricting commission approved legislative maps that were challenged in litigation, but ultimately upheld.


President Barack Obama wins Ohio with 51% of the vote and Senator Sherrod Brown wins re-election by 5 points, but gerrymandering helped provide Republicans 75% of the congressional delegation, 61% of the state House and 70% of the state Senate.


A citizen-led reform effort brought Republican state legislators to the table. The parties involved came to an agreement to reform how congressional maps are drawn, sending the compromise to the ballot.

On May 8, 75% of Ohioans voted for the citizen-led bipartisan compromise to make Ohio’s redistricting process less partisan in 2021. And in 2018, Democrats gained seats in both the state House, and a seat in the state Supreme Court.
