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”.
The other side, the commies, believe they have an answer for every act of crime they commit, they are ideologs and can't/won't be convinced of anything else. They, for all attempts, are "lost" and probably won't see any light from any criminal act (not even if the perpetrators are charged, convicted, and sentenced.
