Not really... If we rule out all votes arriving the day after and counted without poll watchers we win. I don't really understand why people don't get this..

Let's imagine you are taking a math exam - you kick out the instructor and/or any monitors forcibly from your exam. Everyone gets a 100 grade on the exam. Do you think the results of that exam will stand?

Forcibly removing poll watchers is unheard of. We should have had a law that every vote counted must be recorded on video. Social distancing the poll watchers was already insanely stupid. Now that wouldn't be enough to end things. But when they kicked them out - that's pretty unheard of in any functioning country with democratic elections.
