That's why there are a lot of smart Trump supporters that know all this grandstanding and outlandish what-if's aren't going to happen. But if it happens A LITTLE bit in his direction, that might be a good thing.
There is a pattern under Barack Obama, in the eyes of many, that he has directed his branch of government to ignore some laws and enforce others to his liking. More so than any other sitting POTUS ever. This is the EXECUTIVE BRANCH. It is supposed to execute and enforce the law of the land and new laws enacted by congress. Period.
The whole issue of immigration in this country is that there is no law currently in effect. The Department of Justice, through its actions/inactions, is not enforcing any current immigration law. At every step from the border, to the shanty towns, to the civil services available, to the handling of immigrants in custody, to the communication among federal, state and local governments HAVE NOT BEEN DONE PER THE LAWS ENACTED BY CONGRESS. It is and has been chaos for probably going on 20 years, but much more so in the last 7.
There is a backlash against this and the realization the maybe this POTUS has looked the other way on LOTS of laws and has concentrated on laws that really only help his inner circle and agenda.
Trump might never get a new law in congress passed on immigration if elected. I certainly know he'll never get some of the extreme stuff he's been spouting. But I damn well know he'll tell the justice department to follow the laws currently on the books.
