Projected 2026 votes from the On Point simulation: each county's expected turnout times its simulated vote share. Totals may differ from the race total by rounding.

Methodology
Every county is rebuilt by simulating voters going to the polls, 2,000 times, from On Point Polling survey data, past results, and the polling average. How the model works.
