Each party's candidate's share of all presidential votes cast in the county. MIT Election Data and Science Lab, County Presidential Election Returns 2000–2024, compiled from official results. Compare Iowa's counties on these and other figures →

How we show these

Every figure is the state's own certified count, as the Federal Election Commission and the MIT Election Data and Science Lab compiled it, and links to its source. A candidate on several party lines (New York's and Connecticut's fusion voting) is shown once, with their lines added up. We show how many votes each candidate received; we don't explain why results changed or credit anyone for them.
