Undecided voters weigh in on CNN National Security Debate

The eight GOP presidential hopefuls squared off once again in last night's CNN National Security Debate.

The candidates tackled questions on tough foreign policy issues confronting the United States, including the war in Afghanistan, aid to Pakistan and cuts in defense spending. This was the 11th major showdown between the Republican candidates, and the first in which Newt Gingirch came in as the frontrunner.

Alina Cho talks with Larry Arnn and Caroline Elliot, two undecided voters who attended the debate to see if last night helped them clarify their choice for the GOP nomination.
