There may be a teacher’s union in Texas, but it has no power really. Texas is a right to work state.
But Houston is a corrupt city run by affirmative action. Houston proper is not conservative at all. It is quite liberal and very democrat.
Texas is conservative only by the slimmest margin. Dallas, Houston, Fort Worthless, Austin, Salmontonio are all blue liberal democrat strongholds and becoming more blue by the day. Each of those cities is run by “minorities” who are minority in name only and a majority in the cities.
As I’ve noted, Houston will be Detroit in 10 years.
