Missouri's Claire McCaskill is one classy B!#@h. Hat tip to Ben Smith at Politico...

McCaskill was stepping out of her chair at the end of an MSNBC interview, and Romney was up next. She and a staffer unplugged her various wires, and she handed Romney the earpiece the guests use to hear the host.

"I spit on this before I put it in," she said to Romney, with a sweet smile.

UPDATE: Romney spokesman Eric Fehrnstrom emails: "You should have seen what she did to the chair."

Nice one Claire! Way to set an example for the people you supposedly represent.
