Nice little sarcasm there. I didn’t like it when obumber chose which laws he would enforce and which ones he wouldn’t. And I don’t think Trump or Sessions should do it ether. If the laws are unconstitutional, then change them through the courts or what ever means you see fit. What you don’t do is allow some temporary politician to decide what is legal and what is illegal. There has to be some continuity one administration to the next. Otherwise you can kiss any semblance of a Constitutional Republic good bye. Because at some point, the admin will decide the new law is his/her administration is permanent.
You also dodged the 10th Amendment issues. Why, do you not like that Amendment?
