Seems you are working from an incorrect definition of outlier. This poll is out of line by several percentage points from most other polls. There wouldn’t need to be polls showing McCain ahead for this one to be an outlier.
The RCP Composite shows Obama up by 8.1 in Virginia. Again, that is not an outliner but an average of the polls that RCP uses.
Personally, I cannot see Obama winning Va by eight points but it it getting very difficult to imagine how McCain can close that gap.
Worse yet, McCain has to throw money and time into Virginia a state that should have been a GOP Lock.
And at this time McCain is somewhat limited in money and very limited in time.
