He's not the worst, not by a long shot, but he's definitely been inconsistent with his opinions/policy leanings to match different audiences. He has also been very evasive in refusing take a view on big national policy issues that attract controversy, that's politics, but there are figures of any or no party who are more principled in that respect.

I'm sure he'd make for a much better executive branch than most other contemporary GOP figures, but he doesn't really have any consistent platform on national issues beyond being relatively moderate.
