Vote fraud does exist. I have proven vote fraud many times, mostly in IL, apparently many more times than you.
“manufactured votes from fake voter rolls and dead people.”
That is an allegation. It is not proof. Name the dead person, his Precinct where registered. Name the vote harvester and have proof that the vote harvester voted on behalf of the dead. I have done that in the past.
“You saying none of that exists and it is all legitimate?”
On the contrary. I very much know that vote fraud exists. But I know the difference between allegations and evidence and proof.
What type of proof do you need? Do math algorithims count or do you need to actually witness the votes being put into the count with your own eyes?
Is Trump a liar by your definition and 2020 was not stolen since the proof is not good enough? Nobody could prove Stalin stole elections so they were good too by your definition.
