In an August 16 statement Trump wonders "who or what will Biden surrender to next?" Trump has repeatedly said, when asked about his future plans, that we are going to be "very happy". He's also said he'll be returning in some form. Also, among the various Devolution ideas floating around is the idea that while Biden is the President and head of the Executive Branch, that Trump has retained the power of Commander in Chief. There is also this issue: despite the nightmarish performance of Biden this year, a Trump return to power would still not be welcome to a large percentage of the population; as things stand now a lot of people would freak out if Trump returned. Stoked by the MSM it could be bad.
But put it all together: A very serious situation arises, an invasion or attack, and Biden surrenders to a foreign power, surrenders the Constitution. Then Trump returns, announces he still controls the military and that the Constituion is preserved. He would pull the nation back from the precipice of destruction. EVERYONE would be very happy.
Not a prediction. Just spit balling.
I think 20-30% is a large percentage
