Their poll states D+3 (unless that’s a lie). Not much of an over-sample, and certainly better than most that have the election tied or Obama slightly ahead.
In prior days of this poll, it had been as much as + 7 Dem.
D+3 is not as bad as many of the media polls out there.
The sample has whites - only 70% pf likely voters, which is below Gallup’s estimate of likely voters being 78% white.
