In 2001, the Texas legislature deadlocked on new congressional maps.

Actually derailing the redistricting effort, which was one of nearly 20 items added to the special session agenda by Gov. Greg Abbott, would be a herculean lift fraught with risk for legislative Democrats. Delaying the process with a walkout would require strong participation by most of the party's caucus, and could carry steep financial costs.

President Trump said he thinks Republicans could flip a handful of congressional districts in Texas next year through “​​just a very simple redrawing."
