Is this a sign that late breakers are moving to Obama?
The Rand tracker is different in that it follows the same group of voters across the life of the campaign, but the indication that undecideds in their group are moving to Obama is clearly evident in the last three days of data with the biggest movement coming in this morning's report.
This poll has been favorable to Obama throughout. That said, the movement here is significant.
Not much of a diary, but interesting food for thought...
