My guess, is that Trump doesn't have to do anything approaching this. All he has to do, is deliver enough deportation events, depicting human suffering, and maybe go through the motions with a little bit of military, to satisfy his supporters that he is "doing something". Once he does that, the media will play right into his hands, by non-stop condemning and wailing and "I told-you-so" shaming everyone who voted for Trump... and that will be mission accomplished for Trump. His supporters will be satisfied, because they got to see some of the people they scapegoat for the inflation/economy suffer and they will also get crying and gnashing of teeth of the pwned libs. His opponents will also be satisfied, because they will get the schadenfreude of seeing the people who they scapegoat for the election loss suffer the "karma" they deserve and the self-righteous satisfaction of getting to be "proven right" about how terrible Trump would be.
Everyone gets what they want... because at this point... Trump is a supervillain to his opponents... folks don't just hate him... they love to hate him.
They will, but as I reference above, it won't harm Trump in the slightest. It will actually help Trump, boosting his image with his supporters, delivering exactly what they voted for and it will also serve the dual purpose of delivering the non-stop, breathless media coverage that catapulted him into power in the first place. If Trump deports even a tiny fraction of people, it will be covered day and night, by the liberal and moderate media as an apocalypse level event. Meanwhile conservative media will cover it as the heroic, epic fulfilment of a critical campaign promise... all of which will serve to elevate Trump to mythical status among his supporters.
