The first domino in a growing national redistricting battle is likely to fall Wednesday as the Republican-controlled Texas legislature is expected to pass a new congressional map creating five new winnable seats for the GOP. The vote follows prodding by President Donald Trump, eager to stave off a midterm defeat that would deprive his party of control of the House of Representatives. Republicans assigned the Democrats police escorts to ensure their attendance. Some refused and protested on a livestream from the chamber. Democrats are vowing payback, first by asking California voters to approve a retaliatory map in November.
