re: #1 The Vicious Babushka

Based on this metric, the next one to bail out will be Kasich.

Kasich is the front end for some old time mainstream GOP backers, who are using Kasich to attack Trump. I suspect Kasich will continue as long as his backers ask him. Kasich can do his job as Governor and just show up at the next debate, do the talking head shows with video remote, etc.
