Well, yes. Half of everybody is below average intelligence. It’s that fascist bell-shaped curve!
But for whatever reason a large number of voters hate Trump with the heat of a thousand suns. They’d vote for anyone, even one in a coma over Trump. Those voters will never be won over, best we can hope for is they will be so discouraged that they’ll stay at home.
I don’t really think that all that many are true to Biden, but rather true to democrats. They will vote for anyone with a D after his or her name regardless of record or qualifications.
That doesn't work any more, because Democrats have figured out how to manufacture fraudulent ballots for their stay-at-homes - as well as their dead, relocated, and illegals.
A return to voter ID and paper ballots could cure a lot of this - but that would require office-holders to agree to such changes who have zero motive to do so.
