I posted this in a previous bread. Sundance offers insight into the Guarantee Clause in the Constitution. That's where this could go.

I believe there are two paths. One path is where Pence allows a Senator and Representative to announce a dispute to the electors from a state. Both chambers then debate for 2 hours and if they don't agree then the votes from the certified electors of the respective governor are used. That does not favor Trump because these governors were democrats. This is where I think Pence could fuck Trump, by shenanigans that prevent a dispute from being raised. I don't think there's anything Pence can do here to help Trump.
The Guarantee Clause offers another out. And this one does rely on the VP's judgment and power. The Guarantee Clause requires the federal government to protect each state from foreign interference. Sundance explains it a better than I can. In this scenario, and using DNI Ratcliff's interference report assuming it's published before 1/6 Pence can remove the respective electors from the count and this is his power to do so. If that's the case, then the House will vote for president, by state, and that does benefit Trump because there are more R states than B. So, do we trust Pence?
We are in uncharted territory. And SCOTUS won't intervene in either of these scenarios. I think they could intervene by removing electors by the 6th but will they?
