The Battleground poll claims that 15% of respondents have already voted. And that Obama enjoys a 53-45 lead among this segment.
Applying that to the total base of 1,000 respondents, it means the early voting base is around 150. Small sample with an estimated margin of error over 5%. Meaning that a 53-45 lead is "within the margin of error".
Whatever the early vote totals... reports are that there is no obama advantage. Thanks for the breakdown!
