All that being said, VA is a light blue state and Northam was in a significant financial hole after the primaries, so it is definitely possible that when he starts ramping up spending (I presume he hasn't been spending much? Anyone have any campaign finance totals available?) I'll bet that the undecided voters (of whom there are many, in both polls) will probably tilt towards Northam, given the sheer number of Democrats living in Virginia.
Reports for the period ending August 31 were just filed on Friday actually!
