If you wanted to construct a GOP presidential candidate who would doom the Texas GOP long term you couldn't create one better than Trump. He acts like he is still running in the primary. Very little outreach to independents. Conservative democrats, who he seems to be targeting don't exist anymore in Texas. Not to mention majority of youth in Texas aren't Caucasian.
The majority of Texans live in big city metro areas now. Lots of minorities and immigrants. State GOP has done good job of pushing and recruiting minority candidates last decade plus. All that goodwill has been destroyed by Trump's mouth. Dems just run ads that show video and audio of Trump speaking. Since these ads started running the race has tightened up.
