If a democrat were to win in Texas, they would have to be away from the Democrat national party, and Castro already disqualified himself by being the keynote speaker at the DNC.
What if Texans are getting tired of the statewide GOP?
The only real issue Democrats could use against the state GOP right now is their voter ID law which was blatantly discriminatory and struck down.
Keep in mind this will only help gather more Latino voters to the Dems. You just can't rely ONLY on them yet. White Texans are heavily in favor of the Voter ID law, and they vote more. You have to find an issue that caters to them first.
