They're both quite right-wing. The idea that Kasich is somehow moderate is ridiculous. Moderates don't ban rape counselors from mentioning that abortion is an option.
Anyone who isn't left of center isn't a moderate #Atlas
He (basically) agrees with the left on gay marriage(personally against it but legally for it), Medicare, fracking taxes, poverty programs, streamlining military spending... Hmm... Let's look for an issue he's right-wing on.... Abortion! Ah ha! Gotcha now!
I do believe that Kasich, because of his time out of office and his role as Governor of Ohio, is more in touch with what the average Middle American is dealing with than a good many other candidates in the race who have their own (or their contributor's) agendas to advance. This is one of a slew of positives Kasich possesses.
It does kind of shock me that Kasich can't seem to get it through the heads of the collective GOP that he's their best option in 2016. Really, Kasich is almost a Dream Candidate; he's from Ohio, he's currently popular, he's got a lot of experience, but he doesn't have the kind of "insider" tag that can spell death to a candidate. He's got everything Jeb Bush has going for him, while not being a Bush. If his conservative bona fides aren't good enough for the GOP, then it's fair to ask if the GOP is defining "conservative" too narrowly, because Kasich is more of a "movement conservative" than John McCain or Lindsey Graham ever were.
