U.S. President Barack Obama and Republican challenger Mitt Romney face off in front of the cameras for a final time on Monday as opinion polls show their battle for the White House has tightened to a dead heat.

With 15 days to go until the Nov. 6 election, the two candidates turn to foreign policy for their third and last debate. The two candidates are tied at 46 percent each in the Reuters/Ipsos online daily tracking poll, and the debate is likely the last time either candidate will be able to directly appeal to millions of voters.
