Texas Republicans launched a high-risk, high-reward redrawing of the state's 38 congressional districts, a move championed by President Donald Trump to protect the party's narrow House majority in next year's midterm elections.

The Texas GOP knows the risk. In the 2010s, the Republican-controlled Legislature drew political lines that helped pad the GOP’s House majority. That lasted until 2018, when a backlash against Trump in his first term led Democrats to flip two seats in Texas that Republicans had thought safe.
