There was far from a consensus view on who won the debate in the hours after it ended. Two instant polls gave Obama a clean edge over Romney, but the pundit class was, to quote Obama, all over the map.
A bunch of conservative commentators just flat refuse to admit that Romney lost and the story becomes "there was no consensus view on who won." Compare this with the first debate that Obama clearly lost, and the reaction of liberal pundits who not only admitted he lost but commenced with wailing and gnashing of teeth. The mainstream media story there was that "Obama was destroyed in the first debate."
And that is where we are today. Conservatives, using their own media outlets, can totally change the narrative of any story simply by refusing to accept reality. I suppose someday liberals will figure this out, and then reality will truly have no meaning at all.
