On this year's polling and GOTV:
First, I think that the normal adjustments even the best pollsters make to identify "likely voters" was incredibly different in this age of covid. What with tRump setting up his post- election excuse by deriding mail ballots simultaneously with some key states seniors and others historically dependent on it. That is just one of the factors that made this year's polling a bigger challenge. And, IMO, it also makes this year's exit polling relatively useless.
Secondly, I do believe that the tRump cult really got their vote out and hat's off to them. In the Biden campaign, which also--very clearly--did a terrific job getting out our vote, there was a notable effort to promote safety in the pandemic age. The tRump campaign, not surprisingly, didn't give a flying Philidelphia F*#k about voter safety... they just needed to get those sheep to the polls.
Thankfully, our folks were largely comfortable with mail ballots and those that were not showed up on Tuesday.
