Question number two: Aside from the fact his last name is not "Bush", why is Kasich a "better" potential candidate than Jeb Bush?
Kasich has 18 years of national congressional experience on Bush, for those who find such details relevant. If electability is a concern,
Kasich also leads Clinton in his home state,
something that cannot be said for Bush. Bush's Hispandering would only make sense if a) Hispanic-populated swing states had more electoral votes than the Midwestern states that Kasich (and possibly Walker) would put in play, and b) Bush actually demonstrated that he could win said swing states. So far, both propositions are false, which begs the question of why Bush is "better" than Kasich, other than his last name?
