Nice rundown of political facts. 
The 2016 Election Day demographic snapshot became obsolete within days of Clinton's stunning Electoral College defeat. Reaction against Trump has been building steadily across the nation ever since. The turnout surge now is a reflection of that plus disgust over Trump's non-handling of the pandemic. It is not hidden Trump voters who didn't come out for him in 2016 but are eager to do so now. I posted this in late August:
"Reasons why Trump's 2016 upset will not be repeated"

Virtually everything that has happened since then has only strengthened that view.
Under the current set of circumstances we have nothing to fear from over confidence. Broadcasting the handwriting on the wall only serves to depress some potential Trump voters into not venturing out to vote on Election Day during a pandemic. Meanwhile complacency is being rejected by Democratic voters even in areas that are solidly blue. People are standing in lines for hours in New York City to be sure they play their role in demolishing Trump and the Republican Party that enabled him. Emotionally, Democrats are eager to bury this President under a landslide. And we will.
