The GOP party is more moderate at state level in the states you named. But, Jeb or Walker will be the nominee.
Certainly, Clinton will look moderate compared to them.
Lepage is not a moderate and he won. He may have won even with Cutler not being on the ballot. He reached 48%, Cutler voters would have had to both turn out for a race without Cutler AND vote for Michaud by a true, over 60%, landslide for him to win.
Hogan is not much of a moderate in his views either, he simply promised not to touch a whole bunch of things to satisfy his state electorate.
Christie is no teapartier, but is bad at governing.
That leaves only Baker as a northern republican moderate governor who is good at governing.
