Autopen signatures have stood up for decades. This is a non-issue.
Six of the pardons were “signed” in DC while Creepy Joe vacationed in St Crois. A rational person would admit they weren’t actually pardoned by Biden.
A rational person would recognize that there’s no functional legal difference between telling somebody in the office to push the button and a hand signature. I signed all kinds of crap online for a mortgage, I have no idea where the “official record” says those signature happened. And it doesn’t matter.
