 Joining us now is CBS News Chief Foreign Affairs Correspondent Margaret Brennan. Margaret is also the moderator of Face the Nation. So, Margaret, we did have some of those moments in which the president obviously touted extensive foreign policy information, said one of the maybe most memorable lines of the night, control guns, not girls. But he also had those gaffes that we've been discussing tonight. He would sometimes trail off saying a story, say anyway. What's your assessment?
