Trump got higher vote totals and a higher percentage of the vote in the states he won in 2016 but lost in 2020. Biden's campaign, flush with cash, worked heavily on third party voters and senior voters from 2016 to feel comfortable with "good ol' Joe" while the Trump campaign was absent from the fight.
This had an impact - coupled with the trickery of using the looser rules on the the mail-in ballots, harvesting, etc.
... and for the first time ever... Someone not only topped their previous election vote totals, but gained ground in battle ground States...
... and still lost.
If you think there wasn’t MASSIVE fraud via padded computer dumps and mail-in ballot fraud... You’re an idiot.
