You have an interesting theory. Myth Romney saving America from both Warren and Trump. Sound like a Swamp delight.
Romney could be the Swamp’s White Negro, picking up where obama left off.
I expect Romney to run third Party with a Democrat as VP if it is Trump vs Warren. The objective is to keep Trump from winning at all costs. Mitt is delusional enough to believe he can win enough states to actually be President by picking off moderate (cough, cough) Democrats.
