Year by year, 1852 to 2024
Newest first. Rank is the county's place among Ohio's counties that year from most Republican (1) to most Democratic, by lean. Lincoln's 1864 National Union ticket is counted as Republican and Horace Greeley's 1872 Liberal Republican ticket, which the Democrats also nominated, as Democratic; 1852 had no Republican ticket, so it has no lean or rank.
