Kasich was born in PA. Toomey has a tough reelection fight on his hands. It’s certainly not in the PA GOP interest to go to war with Trump.
Out of the 127 delegates currently on this list, 20 of them were elected as delegates in 2012 (out of a total of 59 delegates elected). 2 of them are Cruz supporters now, 5 of them are uncommitted/undecided, and the other 13 say they’ll support whoever wins their district (or are leaning that way).
Cruz has 20 supporters on this list who say they’ll vote for him on the first ballot no matter what. Trump has 18, plus 2 who are leaning/equivocating on him and 2 who say they’ll support him only on 2nd and later ballots (because they’re going with the popular vote winner on the 1st).
Only 1 on this list mentions Kasich as his choice, but he’s still undecided. Even Rubio has 2 committed supporters on this list. I really don’t believe Kasich is going to get the 20% or so the PA polls are saying. Nobody in eastern PA cares about him, I can tell you that. I guess he’s playing for the Ohio border voters?
