That's one take. Here's another, more accurate take: The Pew poll, alone, is meaningless, just meaningless.
Pew's is a national poll, and there's nothing in any presidential election that can be so misleading--and needlessly distressing--as a single poll, except a single, national poll. This contest, like every preceding presidential contest, is not a national contest. It's a swing-state, state-by-state, battleground contest. What some redneck in Texas thinks about Obama or some bluenose in Massachusetts thinks about Romney is as meaningless as ... well, a single, national Pew poll.
It is virtually inconceivable and almost mathematically impossible that Romney can win without Ohio; meaning that we must wait until some credible Ohio numbers come in--numbers sufficiently distanced from the debate rubble's dust.
For the moment, all that Pew has surveyed are national excitability and Obama-camp overwroughtness. Indeed, Sullivan proceeds to flash and then rebut his own:
Obama's performance gave Romney a 12 point swing! ... has that kind of swing ever happened this late in a campaign? Has any candidate lost 18 points among women voters in one night ever?
Of course not, and neither did Obama. Still, Sullivan is correct when he later notes that "momentum counts at this point in the election"; however Sullivan is permitting only Romney's momentum to count. Obama had abundant momentum before the debate. Is that, suddenly--because of one electorally meaningless poll--to be discarded?
Sullivan also characterizes this--"[W]e are told that when Obama left the stage that night, he was feeling good"--as "terrifying." I'd characterize it as ancient history. Obama's aides were panic-stricken, as the NY Times reports, even before the debate's end; they contemporaneously huddled on a counteroffensive and then promptly disabused the president of any "good feeling." Mission accomplished. "He doesn’t brood — he acts," said David Axelrod.
I may yet become excitably distressed, too. This morning I'm not, simply because I shouldn't be. We must first know what's happening in Ohio, as well as Florida and Virginia. And right now, we just don't know.
