Ask them, when you say "no evidence", do you mean that you have personally reviewed all of the evidence, and decided that none of it was credible?
or do you mean that you have literally never seen any of the evidence, and therefore you are absolutely ignorant about all of the evidence?
Because I’m pretty sure the video of an election worker pulling a box full of ballots out from under a table cloth, has never been “debunked”.
I mention that the Secretary of State of Pennsylvania issued the "law" for mail-in voting in PA and only the Pennsylvania State House of Representatives can create laws/legislation. Never had one person come back and prove me wrong. It's a solid one.
