POTUS cannot do as he wants. If he went National Emergency, it'd get held up in courts. Plain and simple. We'd never see the wall at that point. What people dont seem to realize is POTUS needs this to be budgeted. Once it's law, he can augment with funds, but not until it's officially approved.
POTUS is, however, using his position to get the word out, get public opinion I his favor, and a couple of other side agendas accomplished. The wall is the "look here" part of the current stage of the plan.
It would get appealed to 9th circuit, where they'd sit on it until whenever. This wall needs to be passed legislatively. The only way to take the courts out of the equation is Martial Law. National Emergency wont work.
