ROANOKE (November 1, 2012)—Thursday was the busiest day of the campaign for the two presidential candidates, their running mates and their wives, who were visiting seven of the swing states that will help determine next Tuesday which man will occupy the White House for the next four years.

Mitt Romney continued to attack President Barack Obama's business policies, including his suggestion to MSNBC this week that he would create a secretary of business.

Romney told a crowd in Virginia that the nation needs a president who understands business, not a secretary of business.

Mr. Obama, meanwhile, was arguing that Romney is not the agent of change he claims to be.

Campaigning in Wisconsin, Mr. Obama also pointed to the surplus and the new jobs created under Bill Clinton, and said, "We know the ideas that work."

Mr. Obama asked for four more years, saying his administration has met many goals but hasn't completed the changes he's been trying to usher in since his election.

Aides to Romney are conceding that Hurricane Sandy slowed his momentum, although they still say their internal polling shows Romney ahead in some battleground states.

But they're not voicing as much confidence in Ohio or Wisconsin. Romney will campaign in both states in the coming days.
