Those 5 states changed their laws before the 2020 Election. That is why Trump can’t win unless Republicans win the governor races in 2022.
The way democrats cheated in the past was to ‘vote’ the people who didn’t show up to vote. A byproduct of that type of fraud was the ‘dead vote’... NOT because democrats wanted to vote the dead but because the dead never show up to vote.
That said, Democrats might be scared to cheat for the midterms - - they know we’re watching them..
