If scenario A worked out the way you think it would, sure. But It won't. Trump will ruin the Republican brand with the LatinX for years to come, and the dumb Trumpeters will blame the election loss on people like me regardless of whether or not there is a coup. Moderate independent swing voters will respect and thank Republicans for overthrowing Trump, and there will be a huge movement towards whoever that candidate is. Whoever we put up, they will look good in comparison, and the Trump voters can go DIAF for all I care.
Obviously, a Democrat can be president forever, for all you care.
