“If Texas goes blue, there won’t be another Republican president.”
Texas will never go blue. The folks in Amarillo, Lubbock, Waco, Lufkin, Midland, Wichita Falls, and Dumas will always vote solid Republican.
Sure, just ask California.
Maybe, even some formerly conservative universities like A&M and Texas Tech seem to have lost their minds. Are there enough people in the cities you mentioned to offset the larger Texas cities - Houston, Dallas, San Antonio, and Austin? I kind of doubt it.
