I don't think that is true at all. My whole circle IRL is avidly Conservative, and like last time, ain't a one going to vote for Tump. Whether you like it or not, that is indicative of a divided base, at least in Conservative and Christian circles.
I still ain't seen a MAGA hat, or a Tump bumper sticker, though I will admit, I have quit looking... Still see an occasional Cruz hat even now... This is deep Conservative territory, and you would think I would have seen a bunch of em by now. Nope.
So I think you misread Sanford even as you have tended to misread me.
Perhaps I have misread you.
But whether I have doesn't matter one way or the other; neither does it matter how your friends - or mine - intend to vote. What matters is how I intend to vote and why. At this point I have utterly no reservations whatsoever, none. Easiest choice I ever made.
