He could do it but it so early in his administration that it would distract from getting other things done where he needs Congress like tax cuts and getting rid of ObamaCare. I sure would not want his whole first term mired in the immigration issue.
I think a better plan is to get Gorsuch in place first and then prevail in the SC.
I think it would be just the opposite, it would expedite the rest of his agenda. As things stand now the Rats will take him to court over everything.
What he needs is to make sure that the majority of Republicans in the house stay with him to thwart any impeachment attempts.
Very sound advice. Pick the fights you know you will win.
Right now President Trump can rely on his Sec State and Attorney General to whip their departments into compliance to existing laws. Both departments have been operating outside those limits for the past 8 years.
Tactically, rescinding his current directive would neuter the court's intervention without getting bogged down in a constitutional fight. It would also reduce antagonistic rhetoric (OK nothing can stop the verbal diarreah from piglosi and little chuckie schumer) and focus on enabling him to get the new justice(s) into the SCOTUS.
Once all these are done he can HAMMER the bastards. Until then he needs to keep his ego in check and eat the apple one bite at a time.
