I think Texans bought into Trump's conspiracy theory that Cruz's dad aided Oswald in the Kennedy assassination.
They do not care that Kennedy was killed, but their Governor was badly injured in that shooting.
That must be it....that's why Texas overwhelmingly voted for Hillary in 2016. Just as predicted by the Mainstream media polls. Imagine TEXAS up for grabs a day before the election. Instead of worrying about the Cuban losing I would be more concerned about the democrat Senators up for re-election in Trump deep red states. Just say'n...there's no way in hell the republicans will lose the senate.
