From Boca Raton, Florida -

President Obama and Republican challenger Mitt Romney will square off Monday night in their third and final debate, a discussion to be focused on foreign policy, which has already caused fireworks between the two campaigns in recent weeks.

Last week's debate at Hofstra University in New York set up an expected battle over the recent terror attack in Libya that killed four Americans, as many Republicans think Romney fumbled a perfect chance to score points in that debate.

In many ways, foreign policy is much more familiar territory for the President, as most challengers - unless they have been closely involved in foreign policy pursuits - tend not to be as familiar with the issues and the policy nuances.

The moderator of this debate, Bob Schieffer of CBS, has outlined six different segments for the discussion:

* America's role in the world
* Our longest war - Afghanistan and Pakistan
* Red Lines - Israel and Iran
* The Changing Middle East and the New Face of Terrorism - I
* The Changing Middle East and the New Face of Terrorism - II
* The Rise of China and Tomorrow's World

One thing about Bob - I will call him Bob since I sat across from him for about 15 years in the Senate Press Gallery - I'm sure he will try his best to keep the debate going forward on even terms, but not everyone will pleased. That's the way these things go.

Along those lines, if you just go back a few years to 2004 - and even some in 2008 - you will see some Democrats grumbling about Schieffer being chosen to moderate the third debate between President George W. Bush and Sen. John Kerry (D-MA) and then the third debate between Sen. Barack Obama (D-IL) and Sen. John McCain (R-AZ).

Why were some Democrats a bit worried?

That's because Schieffer's brother Tom was picked by President Bush as U.S. Ambassador to Australia, and later as U.S. Ambassador to Japan.

What do you expect tonight? What do you want your candidate to do?
