Recent polls in the U.S. show President Barack Obama and Republican contender Mitt Romney in a dead heat with the presidential election just two weeks away.

A new poll by NBC and the Wall Street Journal shows the presidential race is tied nationally with both Obama and Romney at 47 percent among likely voters, 816 of whom were polled in the survey.

In the same poll conducted mid-September, Obama was five percentage points ahead, but Romney has caught up since the first presidential debate held early this month.

A Fox News poll held in Florida and Ohio, two key battleground states, shows Obama leading in Ohio and Romney in Florida.

The two will hold their third and final presidential debate on Monday.
