Prior to the redistricting, while Republicans received a majority of votes, they held only 11 seats to Democrats 21. Afterwards, as I recall, the Republicans held 17 to the Dems 15.
The fact is that the Dems don't like the idea of their 1990 Gerrymandering being reversed. IOW, these are the kind of people who hit a home run in the top of the inning, then declare the game over and insist that they won.
Republicans now have 21 of the 32 seats in Congress (about 66%). Before is was 15 out of 32. With 57% voting Republican, Texas could have easily lined up 27 to 30 Republican seats in Congress. They bent over backwards not to affect any minority districts and to assure the same or improved minority representation in Congress. The only Democrats who lost their seats were old white men, like Martin Frost here in Dallas.
