After a long day of debate, the Texas House of Representatives passed a Republican-favored congressional map Wednesday evening that could flip five districts red by merging Democratic seats in the Houston, Austin, and Dallas-Fort Worth areas to form new Republican-leaning seats and by making two Rio Grande Valley districts currently held by Democrats more competitive.

Districts currently held by Democratic Reps. Al Green, Marc Veasey, Julie Johnson, Greg Casar and Lloyd Doggett are potentially targeted.

The vote came weeks after state Democrats decried the unorthodox mid-decade redistricting as blatant gerrymandering to increase the number of GOP congressional seats.
