In 2016 the Trump campaign had themes. Like the Wall and ZCHINA. Because Roger Stone was afraid Trump would 'forget' to talk about the important topics and you know policies.
Now the movement is just... put your profession or identity on a poster, add "FOR TRUMP" collect a bunch of vehicles and start blasting the YMCA.
I don't think this nationwide clown circus has been included or accounted for in the polls. As it transcends parties, states and races and some would argue reality.
I think reports that the clowns if they are asked about their voting preference are lying to pollsters is true and the movement and tightening we're seeing in the polls now is Republicans 'coming home' because of the SCOTUS and fossil fuels and no one is prepared for the 'for Trump' clown circus that descends on the polls November 3rd. How that translates to electoral victories is anyone's guess but it'll be a spectacle.
