It’s grandstanding because Kasich doesn’t give a darn about abortion but he suddenly realized that this could help him. So it won’t be his downfall.
That said, I wish Walker had stayed in the game. He was my favorite because he managed to resist very powerful union forces in his state and he also identified the problems. He was a Christian but wasn’t pretending to be “born again” or the follower of some particular pastor or whatever seems to be the current standard.
I wouldn’t vote for Kasich (although I fear he will be the candidate) and I suspect Bush will be gone next week so that reduces the field.
I’d vote for Rubio or Cruz, but I’ll stay home for Trump.
I believe it may be his downfall. But to each his/her own. Whatever you do, take a hard look at Rubio. I live in FL and he is a liar. And dont stay home if Trump wins. I dont like Trump either but he is better than Hillary or Bernie. (Im a Cruzer)
