Republicans have opened up an advantage in a national redistricting battle among states after a pair of court rulings that weakened federal Voting Rights Act protections for minorities and invalidated a key Democratic redistricting effort.
that struck down a Black-majority congressional district in Louisiana has provided grounds for Republicans in several Southern states to try to eliminate House districts with large minority populations that had been protected under the Voting Rights Act.
Meanwhile, a invalidated a voter-approved congressional map that Democrats had been counting on to deliver as many as four additional U.S. House seats. The court said Democratic lawmakers had violated the state constitution when placing the proposal on the ballot.
Legislative voting districts typically are redrawn based on census data after the start of each decade. But an unusual spate of mid-decade redistricting broke out after Texas Republicans last year to reshape U.S. House districts to give the party an edge in the midterm elections. Democrats in California countered with their own . More states followed.
So far, Republicans believe they could win up to 14 additional seats from new districts in Texas, Florida, Missouri, North Carolina, Ohio and Tennessee. Democrats, meanwhile, think they could gain up to six seats from new districts in California and Utah. But those tallies presume hold in November. Historically, the president’s party tends to lose seats in the midterms.
Democrats need to gain just a few seats in November to wrest control of the House from Republicans, which would give them greater power to oppose Trump.
