White House Pushes Texas to Redistrict, Hoping to Blunt Democratic Gains

President Trump’s political team is encouraging Republican leaders in Texas to examine how House district lines in the state could be redrawn ahead of next year’s midterm elections to try to save the party’s endangered majority, according to people in Texas and Washington who are familiar with the effort.

The push from Washington has unnerved some Texas Republicans, who worry that reworking the boundaries of Texas House seats to turn Democratic districts red by adding reliably Republican voters from neighboring Republican districts could backfire in an election that is already expected to favor Democrats.

Rather than flip the Democratic districts, new lines could endanger incumbent Republicans.

But a person close to the president, who spoke on condition of anonymity because the person was not authorized to talk publicly, nevertheless urged a “ruthless” approach and said Mr. Trump would welcome any chance to pick up seats in the midterms. The president would pay close attention to those in his party who help or hurt that effort, the person warned.

At an “emergency” meeting on Monday night in the Capitol, congressional Republicans from Texas professed little interest in redrawing their districts, according to a person briefed on the gathering who was not authorized to comment publicly. The 20-minute meeting, organized by Representative Michael McCaul, a senior member of the state delegation, focused on the White House push.

Representative Pete Sessions, Republican of Texas, said lawmakers plan to gather again to share data and “be on the same page” on the possible redrawing of the map.

“We assured each other, you need to bone up. We need to have a conversation. We need to think about what those impacts would be on the entire delegation,” Mr. Sessions said.
