Voter rolls
Party registration
The U.S. voter rolls by registered party. Thirty one states record each voter's party: blue where registered Democrats lead, red where Republicans do, and grey where the unaffiliated are the largest bloc. Switch to counties, or click a state to read it county by county.

Note
Color reflects registered party, not how a place votes. States and focused counties deepen with the plurality's margin; the national county view shows each county's largest registered party. Only 31 states record party at registration, and the rest are shaded as no party registration. North Dakota, hatched, has no voter registration. Latest official rolls compiled from each state's election authority. · See the 2026 forecast
