US House campaigns are underway. Yet a redistricting battle triggered by Trump rages in some states

Candidates are campaigning and voting is underway in some primaries. Yet a national battle to redraw U.S. House districts for partisan advantage is still raging in some states ahead of the November midterm elections.

Voters in Texas and North Carolina already have cast ballots in primary elections for U.S. House districts redrawn at President Donald Trump’s urging. But the final boundaries for voting districts remain uncertain in Missouri, even though candidates already are filing for office.
