You have it backwards. One cannot assert a problem exists without evidence. Don't ask them to prove a negative, it's literally impossible. You must prove the positive, that voter fraud exists.

If you investigate these things you'll find only 50 people in all of California illegally registered to vote. Just like checking fares on the the train and posting cops on the hov. When trump investigated he found an extremely negligible amount of fraud.

I would love to see any kind of study that has numbers on this, please share if you have one!

The administration has had years and the entire federal legal apparatus at its disposal to prove anything untoward occurred in 2020. Where is that?
