They have been, they have been using 2012 as a baseline which was garbage!! Support hasn’t changed for Trump as much as exit polling of early voting has forced them to change their assumptions.
And the minute they did that, the obvious and undeniable reality started to show up in the polls... There is probably some movement as last minimize deciders are breaking Trump but most of this par 2 weeks is simply the pollsters adjusting their assumptions to the reality that the early voting exit polling is telling them is going on.
Hillary has no path to 270. Never did.
Faux News still has Trump struggling to get maybe 150.
