I dunno.  Maybe it's too subtle and I'm the only one that was amused, but I got a kick out of this response from Obama last night at Columbia:

OBAMA: Well, listen, we had an awful lot of small-town mayors at the Democratic Convention, I assure you. I meet them all the time. And I have---the mayors have some of the toughest jobs in the country, because that's where the rubber hits the road.  We yak in the Senate.  They actually have to fill potholes and trim trees and make sure the garbage is taken away.

Self-deprecating, respectful, and yet getting in the point that up until 20 months or so ago, Sarah Palin's job was worrying about potholes and tree trimming and garbage.
