I find myself having a clinical/academic reaction to this. It was a cornerstone of Trump’s campaign and a big part of what people voted for.
But a lot of the same people were appalled by the child separation policy in his original term, and many of the same folks were outraged but the deportation of one child - Elian Gonzalez - by force back in the day.
Sure, there are going to be people cheering this and ghoulishly enjoying seeing harsh images of deportations, mass incarcerations, etc.
But a lot of Trump supporters are already wishcasting how this will take care of itself via self-deportation before Trump takes office. They will just wake up to find the “illegals” have disappeared from their town without anyone having to suffer any unpleasantness.
We shall see.
