Harry Enten sizes up the race:
Simply put, there hasn’t been a single candidate to come back after trailing by 3 points this late in the campaign in the past 60 years. When I look at the current polling data and put it into this historical context, I just don’t see a Romney victory. It’s not that it can’t happen; it’s just that 3 points is a good lead in a race that has hasn’t shifted easily. Indeed, I wouldn’t be surprised if Obama’s 3-point lead eventually shrank back to the pre-convention numbers that were so stable for so long. That would fit a historical pattern of tightening before an election. But this race is no toss-up: it now leans pretty hard in Obama’s direction.
