President Obama and Republican challenger Mitt Romney will face off Monday night in the final debate of the presidential election. The topic is foreign policy.
Most surveys find Obama and Romney in a tight race, especially in key swing states.
Rasmussen gave Romney 49 percent to the president's 47 percent among likely voters nationwide, while a Gallup poll gave the former governor a 52 to 45 lead.
Gallup has correctly predicted all but three of the presidential races since 1936.
On Sunday, supporters of the two candidates took to the airwaves, squaring off on key issues like Iran's nuclear program.
"Iran thinks they can go much faster and much harder than they used to think they could go, and today they are closer than they've ever been to a nuclear capability. That's very unfortunate," Sen. Marco Rubio, R-Fla., said.
But Chicago Mayor and former White House chief of staff Rahm Emanuel said the Obama administration turned the tables on Iran.
Does a win tonight mean a win in November? CBN News Chief Political Correspondent David Brody, who is in Florida for the debate, has more.
"And the result of that is because of the steady leadership and the course the president has done in building a coalition and forcing now a set of sanctions that Europe would never have considered three-and-a-half years ago, to a point that Iran's economy is on its knees," Emanuel told ABC's "This Week."
Other issues on tonight's agenda include the ongoing conflict in Syria, U.S. foreign policy with China, and the death of Osama bin Laden.
The Sept. 11 attack on the U.S. Consulate in Benghazi, Libya -- a subject that drew fireworks in the last debate -- will likely be a focus again tonight. Republicans have called the incident "exhibit A" of a failed national security strategy.
"If you left it up to this administration to inform the American people, we'd still be believing it was a spontaneous riot spurred by video," Sen. Lindsay Graham. S.C., told "Fox News Sunday."
"There was no mob; there was no riot," the South Carolina lawmaker said. "So, no, I am totally convinced this is going to go down in history as one of the most major breakdowns of national security in a very long time."
Despite tonight's focus on foreign policy, it has been on a back burner for most of the campaign. Some experts say voters are more concerned about the economy and other domestic issues.
