Kasich is not getting out he’s running for VP.
I would enjoy a T/K ticket. But, I have gotten into the beer a bit, so...
RE: Kasich is not getting out he’s running for VP.
If that is the case, Rubio could probably talk to Kasich and ask him to support his candidacy in exchange for making Kasich his VP.
Assuming Rubio is President for 8 years, Kasich can still run for President at that time ( he’ll just be Hillary’s age ).
I’m not endorsing this, but as another tactic, Rubio could talk to Cruz to give way to him so that he can fight Trump one on one in exchange for nominating him to replace Scalia for the SCOTUS.
