Democratic primary elections for 17 of 33 districts in the Ohio State Senate took place on Aug. 2, 2022. Of the 17 districts up for election in 2022, seven had a Democratic primary election with more than one candidate.

The stakes were particularly high for the 2020 elections, and not just for the presidency. At the state-level, some of the most closely watched races were Democratic efforts to flip swing state legislatures blue and take control of the upcoming redistricting process.
