Easy enough to disprove. Do the hand recounts in the supposedly affected states. If those hand recounts aren't done, there's going to be a lot of progressives who spend the next four years looking as lunatic as the "stop the steal" people - with the difference being that there was a really easy way to disprove the lunacy that wasn't used, whereas the "stop the steal" was disproven multiple times and even went to court repeatedly.
So, what I'm saying, just do the damn recount so we can put this thing to rest.
Democrat Strategy: Beg, then bend over and spread wide.
(Not that there's anything wrong with that in your private life, but when you're in public office, you kinda have a responsibility to be representatively picky about who you bend over for)
I don't even think they need to do entire states before deciding whether a widespread recount is needed.
IIRC there are even specific counties with headscratching results in battleground states. Grab a handful of those. If there's fire, it will be found, and then we can mobilize for a wider recount. I'm sure that's still a shitload of work, but prob less than recounting an entire state.
I've been hoping that this is their plan, but I'll admit that (especially given her concession) each passing day I have less faith in this.
The AOC "what happened was massive, you all need to just wait a minute while we figure out what we're doing" (paraphrase) video from a few days ago gave me a little spark of hope, but I suspect even that was not her saying anything other than "we're going to do what we can to mitigate the damage."
