There a few points in there that sound good but aren't....
More votes....populations grow. This is silly like how they kept saying "the most votes in history!" Well yeah and next time will probably be the same.
Lose house win presidency.... congressional districts are not states at large, also senate gains by Dems.
Mail in voters are largely democratic. Counting them after election day, instead of opening them (canvasing) before hand was a noted tactic to try to divide those votes out and then have a court hopefully reject them. When that failed we now see claims that intentionally delayed counting of mail in ballots after election day is supposedly fraud. The GOP pushed them to count after election day because they knew they'd be mostly Dem!
Biden is anemic. Same with his campaign. This guy underestimates how much people hated trump. People didn't come FOR Biden. They came AGAINST Trump.
Independents went Biden. Party registered voters weren't the story of this election.
Before and after election. Easy voting for turn out, hatred of trump, trump mishandling coronavirus are the common cited reasons...
