Ryan looked very young, earnest, serious and determined.
The moderator was not bad and, in fact, put Biden on the spot several times. Her interruptions of Ryan were mostly after he had been speaking for a reasonable time.
Biden only had one moment of incoherent babbling which lasted for 10-15 seconds. But he didn’t step into it too badly given his realization that the media will cover the lie about the request for security from Libya.
I can say that Ryan did not lose at a minimum.
No one can explain the mission in Afghanistan.
