Actually, to get D+8, Dems would have to show up in roughly 25% more than Reps (38%D / 30%R = 27% more Ds than Rs). Obama got +6 in 2012 with massive black turnout. Early black vote (eg: ~-30% in NC) is way down vs 2012.
All I’m saying is that if you torture the data long and hard enough it will say anything you want. :0)
I personally don’t believe the enthusiasm for her is there and certainly not in the way it was for Democrats in 2008 and for Obama in 2012. Hillary generates about as much excitement as a wake.
