I lived in Chicago for a couple of decades. I have seen voter fraud up and close. How do you think JFK won?
Of course it is hard to prove because most states do not require proof of citizenship. That is a straw man response from democrats.
There are many battle fronts in an election.....and many involved...but it’s how the count ultimately is done, by whom, and who votes to begin with.
Whoever controls the count controls the outcome of an election, and this regardless of the voter fraud.
