Where are you voting in the US midterm elections following redistricting? 1 in 10 Americans will vote in a different district

Roughly 34.8 million Americans will find a different congressional race on their 2026 midterm ballots. They did not change addresses. Their homes, streets, and usual polling places remain exactly the same. Instead, the political map shifted around them.

A Protect Democracy analysis shows this affects about 1 in 10 people nationwide. Congressional districts typically change only after a decennial census. Mid-decade redistricting on this scale is unusual. Yet, ahead of the 2026 midterms, nine states redrew their boundaries.

Where the maps shifted most

In Texas, more than 10.4 million, about 35.8 percent of the state’s population were reassigned to new districts.


California followed, with over 9 million residents placed in different congressional boundaries, that is 23.3 percent of its population.

Florida moved another 6 million.

While Texas moved the highest number of residents, Utah experienced the largest proportional change.

The other states drawing new mid-decade maps are Tennessee, North Carolina, Ohio, Alabama, and Louisiana. Each altered its map for distinct legal or political reasons.

The current wave of mid-decade mapmaking traces back to Texas. President Donald Trump pressured Republican state leaders to engineer a more favorable congressional map. When Texas Republicans executed the redraw, California responded by passing its own voter-approved plan.

The dispute widened rapidly. Other states initiated redistricting processes well before the end of the decade. Court decisions forced some of these changes to correct legal violations. Partisan efforts drove others. By bypassing the traditional 10-year waiting period, state legislatures and courts reshaped the national electorate entirely mid-cycle.

What changes at the ballot box

Drew Penrose, a policy strategist at Protect Democracy, notes that sudden boundary changes complicate grassroots organizing. Relationships between representatives and constituents build slowly through local issues and repeated election cycles. When a district suddenly absorbs a massive influx of new voters, that history fractures.

Roughly one-fifth of Americans now live in a district where more than 25 percent of the electorate is entirely new compared to 2024. An incumbent might suddenly represent unfamiliar neighborhoods and different demographics. A voter might see an unrecognizable list of candidates.

Because physical polling locations often stay identical, the change remains largely invisible to the public until election day approaches. Voters in these nine states must check their local election registries to know who they are actually voting for, rather than relying on the boundaries they knew two years ago.
