How concerned are liberals about the presidential race after the first debate? Look no further than The Daily Beast's Andrew Sullivan.
On President Barack Obama: "I've never seen a candidate self-destruct for no external reason this late in a campaign before." And on the prospect of a President Mitt Romney and Vice President Paul Ryan: "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."
