Bill Clinton took the stage this evening to thunderous applause and chants of “Bill, Bill, Bill.” “I’m here, first, to support Barack Obama,” he began. “And I’m here to warm up the crowd for Joe Biden.”

He then touched on the tough battle between his wife, Hillary Clinton, and Obama: “That campaign created so much heat, it increased global warming.”

But he then moved to a more conciliatory tone. “Barack Obama is ready to be president of the United States,” he said, several times, an attempt to downplay the allegations that he and Hillary Clinton made in the Democratic primary, which the McCain campaign is now repeating.

He listed the issues Obama’s ready to take on, including the battle against global warming, and the need reduce nuclear and military threats. Obama will find “economically beneficial ways to fight global warming … and when Barack Obama unleashes them, America will save lives, create new jobs …” he said.
