 Pretty extended exchange between him and the president about when the president called the attack on the Benghazi diplomatic outpost a terrorist attack. And there was some back and forth. Was it the next day or was it ten days? How long did it... That's what you typically think of when you think of flubbed moments at a presidential debate. Again, you don't think of answer after answer where the incumbent is either trailing off and, frankly, not delivering any substance.
