People keep talking about "Federalizing the National Guard" and now you've got other States pledging their NG to Texas in defiance of the Supreme Court (see image).
As far as I can tell, it's a purple state. The right republican would have to come along to pull moderates/libertarians in the state and Trump will only lose the state again - he talked a lot of shit about John McCain; that's not going to go well. Don't get me wrong, every state has it's Trump cultists, but there's just not enough.
