I think Trump now should do a paradigm shift. “Before we discuss illegal immigration and the status for all illegal aliens living in the US, three things must happen. 1) Our southern border is 100% sealed where no one can cross it successfully, 2)all illegal immigrants in US prisons are repatriated to their countries of origin and 3)Sanctuary cities are dismantled.”
If Trump backtracked and said only this, he will be a hero and the one to say what everyone is thinking. And no one, minus conservatives who wouldn’t accept this because of no “get to the back of the line” verbiage, could argue against this position.
My prediction is, whoever says this is going to be the Republican nominee and presents a clear contrast to the Democrat.
