Keep dreaming - it seems to be a happy place for you to fantasize about what he can and can’t do outside the Constitution and whether legal or not will be held up by liberal judges....he wants to do it the right way - which is one of the reasons we voted for him.....right?
Presidents “execute” the law, and the courts, as well as the administrative laws, allow Presidents wide discretion in how the laws are enforced.
DACA was created by Executive Order. The “D” in DACA stands for “Deferred Prosecution.” As you see, the very title of DACA acknowledges that DACA kids should be prosecuted, but their prosecution has been temporarily deferred.
E-Verify was created by an Executive Order in 2007 by Bush Two. It is currently enforced by the Department of Homeland Security for all federal jobs and contractors. At least 23 states use some form of E-Verify for state jobs. All those enforcement policies have survived Constitutional challenges.
Work visa law was mostly legislated in the 1980s and 1990s. Huge parts of work visa law are open to discretionary enforcement by the Department of Homeland Security. By using the political power of the Presidency and by vigorously enforcing EVERY detail of work visa law, Trump could dramatically reduce the number of job killing and wage killing foreign workers.
Liberal judges do not matter if Trump simply enforces the immigration laws exactly as they are written.
Administrative law, which applies to Executive Orders, does not even allow a judge to schedule a hearing if a law is being enforced exactly as written.
The only way lawyers could stop Trump is to challenge the Constitutionality of the law being enforced. That would take years. And while the law itself is being challenged, Trump maintains his full authority to enforce the law as originally written.
