Nope. Reliable sources say 66 percent which is about right.
The Census Bureau reported in April 2021 that its surveys found 168,308,000 registered voters, and 154,628,000 votes cast in the 2020 election.
It’s just numbers. And that’s 92%.
I can’t figure out where these numbers are coming from. I didn’t see any registration numbers in the article you linked. Just “someone” saying it’s 66%.
Where did the 66% guess come from? Hell the number of votes vs. entire population of the US at the time was approx 47%
Please look up number of registered voters in the US for 2020. Because number I saw(and there seems to be a lot of obfuscation.) is 168,308,000 according to Census.
