I agree with all of this, but you are missing the key fact that election results are vetted, there are bipartisan, as well as impartial observers at all counting locations that I'm aware of, and if there's any doubts about the validity of a ballot it's gone over by everyone. I'm nearly as critical of Joe Biden as a republican, which I very much am not, but there's just not anything there to substantiate trumps claims.
There's a reason all these lawsuits are getting tossed. It's because they are garbage.
