As you would have noticed millions more voted at the election more than normally. Its not impossible that had an effect. But to suggest there was fraud when clearly there was not detected is pure sour grapes. If you think that a federal election can be that easily rigged, with millions of electoral staff watching and absolutely none coming forward, you are paranoid beyond anything medicine will manage
Again, that doesn't mean people didnt change how they normally vote.
In fact, I'll bet that is what happened.
What you people are saying is prior to the election someone filled in millions of votes for Biden, distributed evenly to all the swing states, sat them on the floor and nobody saw them, then continued with their counting and miraculously they appeared and were inserted them when everyone had gone home????????
I'd rather believe there's a god than that shit.
