Mass mail in voting was used and they didn't even check the ballots.
In Nevada, the overall rejection rate dropped from 1.6% in 2016 to 0.58% in 2020.
In Pennsylvania, the 2016 rejection rate of 1.0% dropped to virtually nothing at 0.28%.
In Georgia, the 2016 rejection rate of 6.8% dropped to a mere 0.34% in 2020.
“In the 2020 race, Georgia election officials received 1,320,154 mail-in and absentee ballots. If these ballots had been rejected at the 2016 rate of 6.8% instead of the 2020 rate of 0.34%, there would have been 81,321 ballots rejected instead of the 4,489 ballots that were actually rejected.
“Under the conservative assumption that 60% of these mail-in and absentee ballots went to Joe Biden, this dramatic fall in the rejection rate provided Joe Biden with an additional 16,264 votes. That’s more than the margin of the alleged Biden victory in Georgia.”
Meanwhile, the late night ballot dumps in the battleground states had a reality defying 90% turnout for Biden.
Only morons, liars, and people who haven't even given it any thought think the 2020 election was legit.
