None of these judges have ruled it is “unconstitutional”. They have only given a temporary stay. The fact is NOTHING in the constitution allows or gives a right to a non citizen to enter this country. That right is given to the congress and they have that power. They passed the immigration and naturalization act which DOES give the President power to do what he did.
As I said, enjoy you short lived injunction because there are judges out there that do believe in the rule of law and not social activism from the bench.
