Is there a reason we're seeing such a vast difference not only in result but also trend with the tracking polls?
What we can extrapolate, Hillary is likely leading about +3-+5 post Comey crap. Polls' LV screens are failing massively, which is giving us the range of variation.
The only thing we know is that she is leading and that she has done amazingly well with the 20 million early voters who have already cast their ballots. Outside of that, it's a guessing game at this point. Go and vote!
I'll more than likely go on election day rather than early--it's a nearly 30 minute drive with no air conditioning in near-record heat to the early voting here.
