There’s a legitimate technical question about whether the national injunction should remain in place after the Supreme Court has heard the case. It would take five votes for Supreme Court to issue a national injunction itself -- votes that certainly won’t exist. Therefore it’s at least conceivable that the plan could go into place outside the 5th Circuit. http://www.bloomberg.com/view/articl...lips-big-cases
And here even Texas governor says it won't be nationwide
Because politics is being played on the U.S. Supreme Court, I think the best we can hope for is a 4-4 split decision, the consequences of which will mean we will win—but it won’t be a broad-based application around the United States affirming that the president doesn’t have authority to do this. http://dailysignal.com/2016/04/21/te...ation-actions/
