The Pew poll is devastating, just devastating. Before the debate, Obama had a 51-43 lead; now, Romney has a 49-45 lead. That’s a simply unprecedented reversal for a candidate in October. Before Obama had leads on every policy issue and personal characteristic; now Romney leads in almost all of them. Obama’s performance gave Romney a 12 point swing! I repeat: a 12 point swing. Romney’s favorables are above Obama’s now… I’ve never seen a candidate self-destruct for no external reason this late in a campaign before… I’m trying to see a silver lining. But when a president self-immolates on live TV, and his opponent shines with lies and smiles, and a record number of people watch, it’s hard to see how a president and his party recover. I’m not giving up. If the lies and propaganda of the last four years work even after Obama had managed to fight back solidly against them to get a clear and solid lead in critical states, then reality-based government is over in this country again. We’re back to Bush-Cheney, but more extreme. We have to find a way to avoid that. Much, much more than Obama’s vanity is at stake.
