Many of the laws/rules changed in 2020 were illegal and had to be changed back.
It was managed the same way, but again, many of the changes were reversed.
And a lot more observers were deployed this time.
Still a lot of work to be done. Motor-voter laws should reversed, ID should required, mail-in voting should be by request only, ballot harvesting should be illegal, or at least harsh penalties put in place for abuse would be a start.
Oh, and states should not be allowed to use voter registration rolls to draw jurors.
