There's no definitive way to know, if he says he's gay then that's what it is.
However, I've always thought that he fits the bill very neatly, and I certainly relate to him a lot. Despite not supporting him politically, I'll often find myself nodding when he does things, like "yes, yes, I get what you're doing...."
I support the hustle, basically, and I do get a feeling we might be fundamentally similar people. Idk. I don't often get that with homosexuals.
