What will the military, the Supreme Court, and the people eventually do?
The military? Nothing, which is what they should do. We ain't some 3rd-world shit-hole where coup-de-tats happen every 5 minutes.
The SCOTUS? Nothing, which is what they should do. They rule based on the Constitution, and there is nothing in the Constitution about this kind of thing. Even if there was incontrovertible evidence of massive election fraud that proves the election was stolen, there's nothing they can do about it.
The Congress? These are the people that can remove a president, via impeachment. Would the democrats do that to Biden, even in the face of undeniable proof, which does not exist BTW and I doubt ever will? I don't think so. And even if they did impeach Biden, there's no way they can reinstate Trump as he insists. Would we end up with Kamala, or Nancy? Jesus, shoot me now. No. Not happening folks. Like it or not, Joe Biden is the POTUS and will remain so for his 4 years unless he dies or becomes incapacitated to the point were can't do the job.
The people? Well now, we can sure as hell vote the bastards out at the earliest opportunity to do so. As we speak, state legislatures around the country are crafting new laws to hopefully reduce if not prevent election fraud. I do believe it's good to be thoroughly auditing what happened with an eye to stop it from happening again. If you can't trust our election system then how can you trust the elected officials who run it? I don't care where you fall on the political spectrum, if you're not for ensuring election integrity then you're an ideological fool.
