After Biden spoke, Obama made a surprise appearance on stage, one day before he formally accepts the nomination before 80,000 supporters at Invesco Field. Earlier in the evening, former President Bill Clinton abandoned his previous criticism of Obama during Obama’s race with his wife, Hillary Rodham Clinton.

Bill Clinton: “Barack Obama is ready to honor the oath to preserve, protect and defend the Constitution of the United States. Barack Obama is ready to be president of the United States.”

Former Democratic presidential candidate John Kerry also addressed the convention. In his most pointed remarks on Senator McCain to date, Kerry called the Republican candidate’s campaign “insulting,” “pathetic” and “desperate.”

Sen. John Kerry: “The McCain-Bush Republicans have been wrong again and again and again. And they know they will lose on the issues. So, the candidate who once campaigned on the promise of a campaign of ideas, not insults, now has nothing left but personal attacks. How insulting to suggest that those who question the mission, question the troops. How pathetic to suggest that those who question a failed policy doubt America itself. How desperate to tell the son of a single mother who chose community service over money and privilege that he doesn’t put America first.”
