McCain ad: Obama should have picked Hillary

Does this logic indicate that McCain will be picking Huckabee? If not, doesn't that just open him up to being accused of playing a double standard?

And I know they made the "I'm (candidate) and I approved this ad" thing mandatory a few years back, but does anyone get the impression that the candidates aren't really approving the ads? That said, he can't really say he didn't approve it, can he?

Just some random thoughts.
