President Donald Trump has urged Texas Republicans to push through a mid-decade congressional map that would create five additional GOP-leaning districts. A Texas House committee has already advanced draft lines, and Gov. Greg Abbott has authorized law-enforcement action against Democratic lawmakers who left the state to deny the chamber a quorum. The 25-12 Republican advantage in the current 38-seat delegation could widen to 30-8 under the proposal. Trump’s move has triggered a national escalation in partisan redistricting. Republican officials in South Carolina, Missouri, Kentucky, Nebraska, Florida, Ohio and Indiana are weighing similar mid-cycle redraws. In South Carolina, Rep. Ralph Norman is pushing a plan that would erase the lone Democratic seat held by Rep. Jim Clyburn and give the GOP a 7-0 sweep. Missouri lawmakers are debating whether to eliminate Kansas City-based MO-5, the state’s only Black-majority district. Democratic-controlled states are preparing countermeasures. California Governor Gavin Newsom and legislative leaders are studying a map that could flip as many as five Republican-held seats, lifting Democrats to 48 of the state’s 52 districts. Governors and legislative leaders in New York, Illinois and Maryland have signaled support for their own mid-decade redraws, while Democratic groups have filed lawsuits in Wisconsin to force new lines through the courts. Former President Barack Obama called the Texas initiative “a power grab that undermines our democracy,” and non-partisan analysts warn that the emerging tit-for-tat could leave as many as 40 percent of Americans living in districts with little realistic partisan competition. Modeling by election data firm OpenSourceZone projects that Republicans could expand their U.S. House majority to roughly 232-236 seats if only red states act, or to about 227-231 seats if California and other blue states retaliate. Congressional control for the 2026 midterms now hinges on a rapidly moving map-drawing contest, with courts, special legislative sessions and potential state referendums likely to shape the final lines well before voters cast their ballots.
