The fight over congressional maps put nearly 35 million people into new House districts, report says

WASHINGTON (AP) -- The unprecedented spate of mid-decade redistricting for the U.S. House has changed the congressional districts for one-tenth of Americans and significantly altered the makeup of at least one-fifth of districts, according to a new study.
A report by Protect Democracy found that 34.8 million people -- about one in 10 Americans -- now live in a different district than they did during the 2024 election cycle. And about one-fifth of all Americans now live in a district where more than a quarter of voters are new to the district compared with the last election cycle.
The findings display the stark overhaul that partisan redistricting fights kicked off by President Donald Trump last year have caused for Americans across the country. The new congressional maps are increasingly drawn in ways that favor partisan politics over factors like geography and shared communities. That raises concerns among scholars about how the country's hyperpolarized politics are affecting American democracy.
"If this trend continues, it really brings into question whether or not elected officials are really representing their constituents anymore, or if the voters are being randomly picked by mapmakers to squeeze out partisan advantage," said Ben Raderstorf, a policy advocate at Protect Democracy and one of the paper's co-authors.
The bare-knuckled partisan redistricting battle for the House began when Trump urged the Republican-controlled legislature in Texas, the second most populous state, to redraw its congressional map to help the party. The highly unusual plan prompted an immediate response from California, the most populous state, which held a successful referendum to tilt its map toward Democrats.
Other states followed, and Republicans are positioned to potentially gain nine seats because of redistricting.
The Protect Democracy report warns that such partisan tactics reduce faith in American elections generally and insulate incumbent lawmakers from public opinion. That can make political organizing more difficult, the report cautioned, potentially worsening the country's already highly polarized politics. Both parties may also enter a "doom loop" where they embrace more aggressive and frequent redistricting efforts to avoid ceding any ground to their rivals.
In some states such as Missouri, the mid-decade redistricting has created confusion for voters about which district they live in and which candidates will appear on their November ballot. After conflicting lower court rulings, the U.S. Supreme Court last week blocked new Missouri districts backed by Trump that had been used in the primary, leaving the state to revert to its previous districts for the general election.
