BOCA RATON, Fla. (AP) - President Barack Obama and Mitt Romney have toured the site of tonight's debate in the battleground state of Florida.
The 90-minute faceoff at Lynn University in Boca Raton will focus on foreign policy.
Moderator Bob Schieffer of CBS says the questions he'll put before the candidates will reflect "how dangerous the world is in which we live." Topics on the agenda include Iran's nuclear intentions, the fighting in Syria, security concerns in Afghanistan and China's growing power.
Throughout the campaign, foreign policy has been an Obama strength -- but some recent polls show his advantage narrowing. A Pew Research Center poll last month found that 47 percent of those surveyed favored Obama to make "wise decisions about foreign policy," while 43 percent preferred Romney.
Vice President Joe Biden told voters in Canton, Ohio, today that the debates are showing the profoundly different visions each ticket has for leading the country.
