The huge flaw in these polls is using the “likely voter”, which is based on past election models. This election cannot be predicted that way, as the “likely voter” in this election will represent a spectrum of voters who have either not voted before (apathetic) or who had stopped voting in disgust with the canadidates.
I think those two categories break for Trump in a big way. There has not been an election of such a gigantic likely voter shift since the candidacy of Andrew Jackson in the early 1800’s.
It’s a good point. The zeitgeist is in mid-transformation, big time.
