The map overhaul leaves the Houston area with one fewer Democratic district while strengthening Republican strongholds and adding one new red-leaning seat.

The first draft of the lower chamber’s new redistricting map targets Democratic members of Congress in the Austin, Dallas and Houston metro areas and in South Texas.

Republicans are expected to reveal the Congressional lines as early as Wednesday afternoon. Trump would have carried three of the new GOP districts by 10 points, and the other two by more than 15, the person said.
