I've not spent much time in New York, so I don't know Rudy as well as I know Hillary, so she seems more power hungry to me. But what I know about Rudy makes me cringe. From the example I gave in my earlier comment, you can see I despise him for all the reasons Jim posted, plus for abusing the legal system to promote a liberal cause. Rudy's not the worst Republican ([sotto voce] Ron Paul), but he's certainly no conservative.
Suing gun manufacturers was a real piece of work : )
