In a "national security election," pundit Bill Kristol predicts a presidential faceoff between Senator John McCain (R-AZ) and Senator Barack Obama (D-IL).

"We have terrorists to fear," says Kristol. "And we have people who want to kill Americans to fear, and people who want to totally destabilize the Middle East to fear."

"And," Kristol concludes, "I think that's a pretty good argument for McCain to make against Obama."

Fellow panel member Juan Williams disagrees, calling advocating the continued occupation of Iraq and green-lighting the continued spying on Americans part of the "politics of fear."
