On Monday, The Columbus Dispatch reported that former Secretary of State Jennifer Brunner and state Judge John O'Donnell will run as Democrats for the two Ohio Supreme Court seats up for election in November 2020, which could have a major impact on redistricting. Ohio Supreme Court candidates run in party primaries but face off in a nonpartisan general election. Brunner indicated that she plans to run against Republican Justice Judith French, and O'Donnell will challenge GOP Justice Sharon Kennedy.
Brunner had previously won the 2006 election for secretary of state but later lost the 2010 primary for U.S. Senate. However, she has since been elected to the state's 10th District Court of Appeals, serving since 2014. O'Donnell has been running for some time and is making his third attempt at Ohio's high court: He previously lost by just 50.3-49.7 against GOP Justice Patrick Fisher in 2016 even as Trump was winning Ohio by 51-43. In 2014, he lost to French by a wider 56-44 as the Republican wave hit Ohio especially hard, although that was still a narrower margin than every Democrat running statewide for partisan office.
If Democrats win both of these 2020 races, they would gain a 4-3 majority on the state Supreme Court for the first time since the 1980s. Such a majority would have profound consequences for the upcoming post-2020 redistricting cycle. As we've explained in detail, Ohio's new systems for congressional and legislative redistricting passed since the last round of redistricting still give the Republicans who dominate state government the power to gerrymander again. However, a Democratic state court majority could use state constitutional protections to strike down unfair maps in a way that may be insulated from federal review.
