Funny thing is that all those screaming about a stolen election and demanding Biden's removal have absolutely ZERO idea what would happen if this took place. There is no mechanism (short of civil war) that could even pretend to "reinstate" Trump.
That ain't a thing
As a thought exercise only, if somehow the elections were found to be rigged on some massive scale and both Biden and Harris were removed from office - do you know who would become president then? Nancy Pelosi.
Let that sink in for a moment and just imagine the fireworks...
