The timeline is tightening as some states attempt to redraw U.S. House districts ahead of the November midterm elections. Maryland's Democratic effort to reshape districts ended with the legislative session this week. Meanwhile, Florida lawmakers are starting a special session Monday for a Republican redistricting attempt. And Virginia voters are deciding Tuesday on a Democratic plan that could help the party gain House seats. Redistricting usually happens once a decade, but President Donald Trump sparked a mid-decade redistricting battle last year while calling on Texas Republicans to redraw their districts for partisan advantage. California Democrats reciprocated, and other states soon followed.
