With the White House race in its final days, President Barack Obama and Bill Clinton hit the campaign trail together Saturday night.

Clinton, his voice hoarse from a flurry of campaign events, said he had given "my voice in the service of my president." The former president vouched for Obama's economic agenda, saying he had done a good job with a bad hand.

Obama, in his fourth rally of the day, sought to draw a connection between the flush economy Clinton presided over and his own policies for a second term, including increasing taxes on upper income earners.

The joint rally drew more than 24,000 people to an outdoor arena on a chilly November night. Obama and Clinton will campaign together again Sunday morning in New Hampshire.
