Could something like this happen? Biden is installed as the next president; and then, a few months later, a civil suit reveals that, yes indeed, the vote was flipped. Think about that. The moon comes up in the morning and sun comes up at night.
“Today, it was revealed that the Biden-hαɾɾιs ticket lost the election by three million votes. Trump won with 320 electoral college votes…”
Hate to say it like anything, but by that time, it'd be too late. Once the electoral college votes, that's it.
The doo-doo would indeed hit the fan, but it wouldn't undo the election. At that point, it would behoove the Republicans to harp, and harp, and harp endlessly, on what happened, and how the Democrats (and the vote counters!) aren't to be trusted. It very well might be the time for Trump and Company to buy Newsmax, The Washington Times, iHeart Radio, or whatever, and create a media network to counter the MSM --- "MAGA Net", anyone?
