With one debate left, President Barack Obama and challenger Mitt Romney are retreating from the campaign trail to beef up on foreign policy.
They're leaving the work of courting voters to their running mates.
Monday's debate at Lynn University in Boca Raton, with its focus on international affairs, is the third and final between the two rivals and comes just 15 days before the election.
President Obama left Friday for Camp David, the presidential hideaway in Maryland's Catoctin Mountains. He will remain there with advisers until Monday morning. Romney will spend the weekend in Florida with aides preparing for the debate.
Romney's running mate, Paul Ryan, planned a campaign stop in Pennsylvania on Saturday. Vice President Joe Biden rallied in St. Augustine Saturday afternoon.
President Obama is scheduled to make a post-debate rally stop in Delray Beach on Tuesday.
