Virginia voters on Tuesday will decide whether to ratify an unusual mid-decade redrawing of U.S. House districts that could boost Democrats’ chances of flipping control of the closely divided chamber, as the state becomes the latest front in a national redistricting battle.

A proposed constitutional amendment backed by Democratic officials would bypass the state’s bipartisan redistricting commission to allow use of new congressional districts approved by state lawmakers in this year’s midterm elections.

The referendum tests Democrats’ ability to push back against Donald Trump, who started the gerrymandering competition between states after successfully urging Texas Republicans to redraw congressional districts in their favor last year. Virginia would be the second state, after California last fall, to put the question to voters.
