I don't know anything about this guy but from your description he sounds like Eliot Spitzer pre-prostitute days. Before Spitzers fall he was widely regarded as a straight arrow but also pissed a lot of people off with self-righteousness. Does Earle have that problem?
Prostitutes or pissing a lot of people off? His daughter is a Travis County judge, so I guess he stays on his toes. Ronnie Earle is an equal opportunity pisser-offer. Sure, he's a solid Democrat, but if you break the law, he doesn't care. He'll "take no prisoners" to get justice. Personally, I like that about the guy.
