Mostly that shows both major parties getting a bigger share because the third party cratered. Gary Johnson voters who split somewhat evenly between Biden and Trump.
It clearly shows that “Dur Dominionz” didn’t rig the vote in Wisconsin.
If you add up the vote in the counties that used the machines and compare the net vote in 2016 and 2020 you will see that Trump netted 16000 more votes across those counties.
All things being equal, he would have won Wisconsin by more votes (38000) than he won it by in 2020 (22000).
However all things weren’t equal. Two counties had a massive Democrat overperformance, Dane and Milwaukee.
Neither county uses Dominion machines.
It was the late mail in paper ballots in Milwaukee that put Biden over the top.
Pennsylvania looks nearly the same when you crunch the numbers.
