From WaPo's retrospective on the Scozzafava mess:
"There is a great song called 'Coca Cola Cowboy' and I believe that's what we have here. She was a Republican as long as it enhanced her electability," said Armey, reached while petting a goat at his Texas ranch. "My guess is she made a deal with Chuck Schumer or the White House that will eventually show itself to us."
The "goat" bit is what surprises me, of course.
