Federal Judges have to interpret the Constitution ... If the reasoning behind Trump's EO was deemed unconstitutional, then they get to strike it down.
Works both ways. If the reasoning behind Obama's executive order is unconstitutional then they get to strike that down- and that is coming.
You stated: "federal judges have to interpret the constitution." Not to get too persnickity but federal judges have to interpret statutes too, not just the constitution.
In this instance the court is required to do both. It must determine whether immigration laws are constitutionally within the jurisdiction of congress or the President- hint, that is a one second exercise. Then, the court must determine whether Congress has in fact already passed legislation governing who is here legally and who is not- another one second exercise. Those laws are already on the books and have been for quite a while.
The Constitution requires the President of the United States to "take care that the laws of the United States be faithfully executed." Lefty clowns and the uninformed (often the same) are using the lefty media to make the case that Trump is attempting to do something unconstitutional. That could not be further from the truth. He is attempting to implement the law of the land as enacted by Congress- as he is required to do by Constitution and is properly subject to impeachment if he does not. Obama had no constitutional authority whatsoever to enact immigration "law" through executive order for the purpose of doing what he could not get Congress to do.
Have y'all not seen the numerous youtube and other compilations that show Obama himself - a former constitutional law instructor/not professor- saying repeatedly that he would like to be able to do what he eventually did but that he was not king or emperor and lacked the constitutional authority to do so?
DACA's going down. These scattered district court opinions only hurt the cause of those who want to put a deal together. The dems should be/should have (probably too late now, as I said long ago, they will fuck it up) been using this timeframe to work a deal with congress.
The dems demanded relief for 800,000 daca recipients. Trump flushed his entire base down the toilet and offered up twice that, plus a path to citizenship. Then, the lefties said "no", you racist, nazi scumbag. Wayyy to go lefties. As I said, I knew you could fuck it up and it was never about helping hispanics anyway. Trump flushed the bullshitters out and exposed them for what they are.
Trump needs to faithfully execute the laws or be impeached. He is required by the the constitution to implement the laws of Congress which is trying to do with immigration. Not some campaign strategy of Obama which he thought Hillary would inherit all while knowing it was unconstitutional.
