Are they serious? One of the best moments in recent debate history? The clue to the meaning here is in deciphering exactly what they mean by "recent" - that is an ambiguous word that can mean anything from "in living memory" to "this morning." Putting this comment into context reveals that by "recent" they almost certainly aren't going any further back than the first Presidential debate. That is the only meaning that can be given to the term "recent" as they've used it because, by comparison to Obama's dismal performance in the first debate, anything Obama did in the second debate - including blowing his nose or clearing his throat - is, by comparison, a better moment.
That's the thing with democrats/progressives: you always have to carefully decipher how they're using ambiguous words like "recent" or "fair" and you cannot simply assume they're using those terms in their plain, everyday, ordinary implied meaning.
