I wrote a post on him in April because he has such an amazing biography (not in a good way). I included some background about the rape in the post.
I find the support he enjoys utterly bizarre. He didn't just sleep with a 13 year old girl, he drugged her as well as using his position as a successful film director with influence over the girl's career.
I'm not sure it goes without saying, but to many of his supporters, being a conservative or libertarian is a greater crime than the one he committed*.
*I don't want to deny at some some ambiguity regarding the nature of the rape, but he did confess and though he has suggested that he was the victim of a bit of a witch hunt, Googling around hardly makes me more sympathetic to him. Even from stuff he said himself, he doesn't sound innocent at all.
