I've never met or heard of a politician of any stripe who lacked ego or arrogance. It seems to be a prerequisite for success.

Call me disingenous (oh yeah, you already did!), but I don't see arrogance or even abrasiveness as a big detriment in someone I've voted to represent my interests in City Hall or higher up.

I've met Sam and worked with him. I can't say that I've witnessed or heard of him being "abusive", but I agree with you about the other stuff you say. I just don't see it as a problem.
