Presidential debate: Mitt Romney and Barack Obama face off a final time

presidential-debate-mitt-romney-barack-obama.jpg President Barack Obama and Republican presidential nominee Mitt Romney square off Monday (Oct. 22) at 9 p.m. ET/6 p.m. PT in their final debate before Election Day on Nov. 6. With just two weeks left until the election, the stakes are high for these candidates, so what can viewers expect during the final showdown?

Here's a basic rundown:

"Face the Nation" host Bob Schieffer will be moderating the debate, which takes place this time at Lynn University in Boca Raton, Fla. The focus will be on foreign policy, and the format will be an unstructured discussion similar to the first debate.

The candidates will have 15 minutes to answer each of six questions -- assuming they can get to all of the questions, which didn't happen during the first debate.

Barring any breaking news, the discussion topics will encompass the following six themes:

- 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

The debate is expected to last 90 minutes, and if you're not near a TV to watch the debate on the myriad stations airing it live (ABC, CBS, NBC, CNN, Fox News, Univision, PBS, for example), then you can watch it on YouTube via the Politics Channel, ABC News and the New York Times.

Or you can just follow along with the play-by-play on Twitter, which is sure to offer nearly as lively a conversation as the debate itself.
