did 150 percent of voting age americans cast a vote in this years election?

Not at all. On the contrary, 2020 voter turnout is estimated at less than 70% of eligible voters. (Which is actually quite good - usually it's around 60%)

Silly you, playing right into Trump's hands. 

This was his plan - to make his people doubt the outcome. 

Kinda like when a spurned lover kills their intended, "If I can't have you, no one can!"

More crazy made up stories,  no one gets to see all the votes to tell people who others voted for, a number of people only vote for the presidential race as they can't be bothered to go all the way down the paper to pick people they dont' know.    And you are wrong, in states where the mail in ballots are counted after the in person votes, most are democrats, as Trump told his people not to mail in vote- although HE DID. and Democrats encouraged people to vote by mail to avoid lines and contact during this covid virus.       

I know. Its amazing. All zero of them.

Give me proof for that claim right now. Saying it will be provided later is an obvious cop out.

That's just the states reporting absentee ballots you dork.

Did you hear that on Boogaloo Fakenews or Butthurt Descendants Of The Confederacy?

Nope.  I presume you know (1) Trump telling his folks to vote on election day, thus ensuring mail-in votes are more heavily democratic; and (2) several states have a law saying mail-in ballots cannot be processed until election day, when poll workers are busy, so the mail-ins wait until later days.  BTW, the details of when a tired person updates a website isn't terribly meaningful.

Cite the proof of your stupid claim.
