CHARLESTON, SC—After spending two months accompanying his wife, Hillary, on the campaign trail, former president Bill Clinton announced Monday that he is joining the 2008 presidential race, saying he "could no longer resist the urge."

"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."

"Damn, this feels good," Clinton told supporters as he shook hands in Charleston Monday.

He continued, "It is with a great sense of relief that I say to all of you today, 'Screw it. I'm in.'"

In a show of respect, Clinton then completed his introduction of Hillary Clinton, calling her a "wonderful wife and worthy political adversary," and warmly shook her hand as she approached the podium. A clearly shocked Mrs. Clinton got halfway through her speech about the nation's obligation to its children before walking briskly offstage.

A spokesman for Sen. Clinton's campaign had no comment.
