For one, Nolte is conflating polls taken just before the election with polls taken months before. As the pollsters approach the moment of truth, they removed most of their number fudging. Either that, or Clinton’s double-digit lead collapsed just days before the election, because voters deserted her suddenly, en masse. Those Hillary supporters were sure fickle.
I still say it was Tim Kaine’s disastrous VP Debate that clinched it. He looked like a clown.
