You will not prove the fraud.
Look at the results: Trump loses, Dems pickup 3 senate seats, but GOP picked up 14 seats in the House.
How does that happen?
Well, if blue areas had their ballot boxes stuffed with votes, it would affect statewide races only. Congressional races would not be affected.
So, if Democrats simply cast votes on behalf of every registered Dem voter (which is what I suspect happened) in blue precincts, you would be unable to say that vote is fraudulent because it is linked to a registered voter.
You cannot ask that voter if they voted or who they voted for. That is illegal.
But every ballot would match a registered voter. If a voter went to the polls or dropped a mail ballot, you would have two, but there is no way to track that.
Your audit would fail right there.
Vote by mail allowed votes to be cast on behalf of every registered voter, whether they voted or not.
> “You cannot ask that voter if they voted or who they voted for. That is illegal.”
Asking one on one if they voted is legal.
Online records show whether a registered voter voted.
Canvassing in-person to ask if the online record is true is legal and has been so asked extensively. The results show insofar as the Nov 2020 election that massive fraud occurred.
You are correct that statewide races are rigged, notably by boiler-rooms in urban areas
