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 in Texas currently hold 25 of the state’s 38 seats, and the new map ups the total they could win to 30. All of those new 30 seats were won by Trump in November by at least 10 percentage points, leading to conservative optimism they can hold them even in what’s likely to be a tough midterm environment for the party.

Texas state Republicans on Wednesday released a new draft congressional map, which makes significant changes to Democratic-held districts.
