Hamilton County anchors southwest Ohio with more than 845,000 residents and delivered a 14.9-point Democratic margin in 2024, a dramatic reversal from its long Republican lean driven by suburban realignment in and around Cincinnati.
The 2008 election was the turning point, when the Democratic candidate carried the county by seven points. The 2024 margin was fifteen points, in line with the county's new direction.
The demographics suggest why. A population of 830,774, a 63% non-Hispanic-white share, and a median household income of $72,470 situate the county in the broader realignment patterns of recent cycles. The county's voting pattern over the last decade is most similar to that of Henrico County and Loudoun County.
