Ryan won that debate. The tactic Ryan took was the right tactic, because even the most liberal journalists were calling out Biden for coming across as a jackass for laughing at the most inappropriate times, like the fact that Iran has nukes, (heeheehahahahohoho). If Ryan, or anybody, had gotten all-powerful and told Biden to shut his pie hole, if he had nothing to say, the media would have played if as though Ryan was too temperamental and reactive to be a sober choice for VP.
Ryan did good. Many of the other factors were simply stacked against them this election season. You can have the perfect candidate, and still lose.
Ryan is non-confrontational. Just dont try to snow him in debate. I dont know what options he has at this point, however.
