"My fellow Americans, I am sick and tired of not being president," said Clinton, introducing his wife at a "Hillary '08" rally. "For seven agonizing years, I have sat idly by as others experienced the joys of campaigning, debating, and interacting with the people of this great nation, and I simply cannot take it anymore. I have to be president again. I have to."
He continued, "It is with a great sense of relief that I say to all of you today, 'Screw it. I'm in.'"
