Right. Actually they will try to oppose him on everything no matter what but what may be different here is Trump's original intent to "ban muslims" helps these judges feel sanctimonious and further justified in their minds in opposing a lawful EO. Banning muslims works for me but it would never pass legal muster and Trump ran as a law and order President. He could do a 'Jackson' and thumb his nose but why play that card so early?
Trump needs to get the SC justice installed and prevail in the SC ... or implement extreme vetting immediately which negates need for the ban ... or (as another Freeper suggested) just temporarily ban all immigration coming from all countries. Heck no discrimination there. Just shut it down. I sort of like the last option myself. Double down.
In fact, it does pass legal muster.
I think it's US Code 8 (I forget the section number) that gives the President the blanket authority to prohibit entry of any class or type of aliens, if he feels it is in the national interest to do so.
The power of the President under that law is broad, sweeping, and absolute.
