Clinton is spending $ in TX. Here is Nate Silver's electoral map, and he's been the best at predicting the last 2 election cycles:

The question is if it will be enough of a mandate to squelch notions of "rigging," (which is ludicrous, btw.) At this point, Trump appears to be making no attempt at reaching out to undecided voters, only to shoring up his base. My mother, ever the Oracle, says that he's priming them for his Media empire, TrumpTV in conjunction with Breibart, or whatever, post-defeat. Mark her words.
If anything, disenfranchisement is more likely to happen to minority voters, since this is our 1st presidential election since the Voting Rights Act was essentially neutered by the Supreme Court in 2013. Trump is using racially-coded language to stir people up to monitor the polls on a vigilante basis, and some of his people are taking this to heart. They really can't, though, and any attempt would be a federal offense. I hope that our election day is peaceful, as so the transition.
