As Texas Republicans battle with state House Democrats, who fled to block the GOP’s ability to pass new congressional maps, there’s an intraparty skirmish proceeding just as fiercely on the sidelines: the state’s contentious Republican Senate primary.

Texas Attorney General Ken Paxton and the man he is vying to unseat in next year’s Republican primary, US Sen. John Cornyn, are both using the powers of their offices to try to pressure the Democratic lawmakers who fled the state to prevent a vote on a GOP-led redistricting plan.

Democrats who left the state have shown no signs of buckling for now: A group was scheduled to appear later Friday with California Gov. Gavin Newsom in a public show of support for the walkout.
