The latest Gallup Poll Daily tracking report, taken from 10.5 to 10.7 (i.e., before last night’s debate) shows Barack Obama with a 52% to 41% lead over John McCain. Between McCain’s “that one” gaffe, his leaving the studio right after the event (while Barack and Michelle stayed and chatted), and the worldwide economic calamity vibe it really does feel as if the ship has sailed on the 11.4 outcome. The lead may expand a bit in the next poll, given the general consensus that Obama “won” or at least did better last night. The only thing to factor in on top of this is the Bradley effect.
