Voter rolls by state

Each state is colored by its registrations as a share of the Census count of adult citizens, using the state’s own registration count. Hatched states have no registration file loaded yet.

Registrations ÷ Census adult citizens, by state 10 of 47 states over 100%. Hatched: no registration file yet. Florida, Mississippi, Nevada, Utah, and Wisconsin count active voters only, so their shading leaves out inactive registrations. Click or tap a state for its page.

The swing by state

Each arrow leans left and blue where a state moved toward Democrats between the 2024 presidential vote and its 2026 race, right and red where it moved toward Republicans. Longer arrows mean bigger moves. Each state page names its race and draws the same arrows county by county.

Change in the Democratic share of the two-party vote, 2024 to 2026 38 of 39 states with a two-party race by county moved toward Democrats. Hatched: no county results for a two-party race yet.

What we have, what’s missing, and why

The registration counts and the 2026 results on these pages come from files each state’s election office posted, on its own site or the results site it links to. So far that gives registration files for 47 of 50 states and 2026 county results for 39. Here is what each covers, and for each state still to come, the reason.

Registration files

Loaded for 47 states. Each is the newest file the state had posted when it was fetched, so the dates differ. By the date on the file:

The other 3 states:

  • No voter registration · 1 state.

    • North Dakota has no voter registration, so it has no rolls to set against the Census count. Source
  • No current file posted · 2 states.

    • Massachusetts’s registration statistics page has no 2026 counts yet; its newest are from 2025. Source
    • Missouri: The newest county registration file on the Secretary of State’s site is from 2022. Source

County results

Loaded for 39 states, each for the race its page names, as the state’s file labels them:

The other 11 states:

  • No file of the general election results posted yet · 9 states.

    • Connecticut’s certified results database holds no rows yet for the November 3 general election. Source
    • Florida’s results site does not list the 2026 general election yet. Source Next: November 16, county returns.
    • Illinois’s State Board of Elections posts county vote totals after its canvass; until then, each county’s election authority posts its own. Next: December 4, the State Board of Elections’ proclamation.
    • Maine’s Election Results page has no November results yet. Source Next: November 23, official results.
    • Massachusetts’s results database has not added the November 3 general election yet. Source
    • Mississippi’s Secretary of State site lists no 2026 general results yet. Source Next: November 13, county returns to the Secretary of State.
    • New Jersey’s results archive does not list this year’s general election yet. Next: November 18, county boards of canvassers meet.
    • New York’s election-night results site has no download this build could find, and its unofficial counts leave out a significant number of unscanned emergency ballots from Westchester. Source
    • Wisconsin’s Elections Commission results page has no November results yet. Source
  • Results that do not make a two-party map by county · 2 states.

    • Missouri’s unofficial results report Kansas City as its own jurisdiction, apart from the counties it lies in, so the county map waits for results that assign its votes to counties. Source
    • Montana: in its US Senate race, candidates other than the Democrat and the Republican together drew 193,577 votes, more than the Democrat’s 59,960, so there is no two-party race by county to draw.

US House, and what comes next

US House district results are loaded for 41 states, and the US House tile above sums their district votes: Alabama, Alaska, Arizona, Arkansas, California, Colorado, Delaware, Georgia, Hawaii, Idaho, Indiana, Iowa, Kansas, Kentucky, Maryland, Michigan, Minnesota, Missouri, Montana, Nebraska, Nevada, New Hampshire, New Mexico, New York, North Carolina, North Dakota, Ohio, Oklahoma, Oregon, Pennsylvania, Rhode Island, South Carolina, South Dakota, Tennessee, Texas, Utah, Vermont, Virginia, Washington, West Virginia, Wyoming.

How this was built

Registrations are each state’s own count, under the state’s own label; where a state splits active and inactive voters, the map uses the total, as the viral maps do, and the state page shows both. Adult citizens are the Census Bureau’s citizen voting-age population from its special tabulation of the American Community Survey for 2020 to 2024. A state’s ratio is the sum of its counties’ registrations over the sum of their adult citizens.

The swing is the Democratic share of the two-party vote in each state’s 2026 race, minus the share in the 2024 presidential race, in percentage points. The race is the US Senate where the Democrat and the Republican each drew more votes than all other candidates together; otherwise the governor’s race; otherwise the US House. The House tile adds the Democratic and Republican House votes in the states whose 2026 district results are loaded, beside the same states’ official 2022 totals from the Federal Election Commission.

These pages describe the numbers. They are kept apart from the tests we registered in advance for our own analysis of the 2026 returns. Unofficial results move during the canvass, and the pages are rebuilt as states certify.
