Texas has been gradually changing over the past decade or so.
Trump will probably still pull it out - but it's only a matter of time. When that state truly is purple, or even blue, it will be a real game changer.
Changing, but at a snails pace, Cornyn is heading the ticket, and he is popular, besides, the State Gov't is doing its best to disenfranchise as much voting as they can, I'd believe Georgia could go Blue before Texas, and Georgia ain't doing it this year
