There were 168 million registered voters in 2020. Trump received over 74 million votes, and if the vote count can be believed, Biden received 81 million votes. That’s a total of 155 million votes cast. That’s a 92% turnout!! The average turnout for a presidential election in this country has been between 55%-62%. That alone is grounds to believe the 2020 election was fixed!!
Pence disagrees with you.
Well, that and the 15 million votes counted but with no supporting ballots———
Voter turnout percentages are based on ELIGIBLE voters. Not registered voters. And if you go to the trouble of registering, you’re probably going to vote.
The above source, which gives state-by-state totals and citations to Sec State sites, shows 214 Million. It is true that some general sources say 168, but that seems to be an error, unless you can provide a state by state table that differs from the 214.
And your figure of 55-62% turnout being usual is a figure for turnout as a percentage of ALL eligible or voting-age adults, many of whom are not registered. For a presidential election, turnout can run well over 80% for educated areas with voter rolls that are well-maintained -- on down into the 60-70% range for less educated or lazy (stuffed?) voter roll areas.
