One can only conclude that his donation history is acceptable.
I don’t know about that end of it. I can tell you this much, however. His initial claim to be a big Palin fan was accepted, and it saved his bacon. Subsequently he was hammered over the fact that he slavishly supports everything Palin ferociously opposes. In time his incongruous pro-Palin tagline disappeared. Perhaps he simply realized the futility of pretending to be a conservative. No-one who has followed his posting history even loosely is buying that whopper.
