I think we'll turn sooner. We came close to electing Beto which made folks realize it was possible. But Cruz is an easier target statewide than Cornyn. What is helping are the tech companies coming to Texas like Tesla and bringing in or keeping here, younger, better educated, workers.
The divide is really more rural voters who don't need, want, or accept government interference and urban centers which do. Government health care? Stitch yourself up and get back to work. Taxes for stuff we'll never need or use? No. Tell me from 3,000 miles away what I can and can't do on my own land? Hell no. That self reliance runs deep. Classic small taxes, small government works the best for those people.
Working the Beto campaign was a real eye opener. I respect those voters more.
