Boehner stumps for McCain in Oxford

"Now, listen, I've voted 'present' two or three times in my entire 25-year political career, where there might have been a conflict of interest and I didn't feel like I should vote," Boehner said. "In Congress, we have a red button, a green button and a yellow button, alright. Green means 'yes,' red means 'no,' and yellow means you're a chicken shit. And the last thing we need in the White House, in the oval office, behind that big desk, is some chicken who wants to push this yellow button."
