Hello, frens.
About nullifying fraudulent states' election/delegates:
If you nullify the election (only) in states that would've given the election to Trump, you're simply handing over the election to Biden, on a plate.
And even if the election was to be repeated in those states, its results would forcibly be influenced for knowing its outcome in other states; that's the reason why elections are held simultaneously across the country.
So the only legitimate way out of this mess would be for the election to be nullified nationwide, and a new election being held after this one being throughly investigated and all the culprits outed, which would mean at least months away.
