I think Rudy is, in his way, more dangerous than a tyrant or thief. He is neither, IMO. I don't think he's in politics to oppress people or to enrich himself. I think he has control issues - a need to be in charge and a conviction that he's right which go hand-in-hand. But I also think he's a reasonably well-intentioned, if misguided, statist. I feel more or less the same about Hillary, though she gives me a bit of a cold chill.
Either one is worse than a tyrant or a thief. It's sometimes easier to protect yourself against those who would do you harm than those who want to help you, but cause harm to which they seem blind.
