"But it was a crowded field!" Yes, it was. Let's add 100% of Warren votes. That brings it to 602,626, an increase of 0.6%. 4/
Hillary 2016: 581,775 MI primary votes
Biden 2020: 838,515 MI primary votes
That's a 44% increase for a candidate who's arguably even more "establishment" (36yrs Senate, 8yrs VP) than Hillary (8yrs 1st Lady, 8yrs Senator, 4yrs SoS).
Over 6,000 people (presumably those college kids in the video clip) waited until there was less than 3 1/2 hours left on election day before even *showing up* to REGISTER to vote.
