Explore voting trends by county
Compare official election results without relying on permanent county labels or an undated political map.
County voting patterns depend on the office, candidates, turnout, and year. To understand a trend, compare the same type of contest across multiple completed elections using certified totals.
Start with 2025
Use completed statewide election results as a recent baseline.
Open 2025 county results →Compare older cycles
Choose the same office and election type from the state archive.
Browse historical results →Check turnout
Vote share can move because turnout changes, even when total votes rise.
Open election data index →2025 certified governor results by county
Open the county PDF for the actual vote totals, then compare the same county with the 2021 governor results.
A sound comparison in five minutes
- Select two or more completed, certified elections for the same office, such as governor.
- For each county, record total votes and each candidate’s vote share from the official county table.
- Subtract the earlier share from the later share; label the result a percentage-point change.
- Check turnout and county population context before interpreting the shift.
- State the exact contest and years. A presidential pattern is not automatically a county or legislative pattern.
The former unsourced “safe / swing / leaning” county labels have been retired. Use the linked official datasets for a defensible comparison, especially before publishing a map or forecast.
