I know very little about Savage. His show plays late at night here and I've only heard him once.
I do think he owes an explanation for his donation to Jerry Brown and I'm disappointed that his fans at FR aren't asking for one.
Why would ANYone have to apologize for donating to any particular candidate? He, or his wife likes the man, and prefers him over the opponent. I would never vote for him, but then again, I never met him.
