Stephen Miller’s piece on the home page listing some of ”The Debate Questions CNN Should — but Won’t — Ask” makes fun reading. But there are plenty of other opportunities to make Hillary and the rest squirm, immigration being chief among them.

We know all the candidates on the stage tonight are in favor amnesty for illegal aliens, so my colleague Jon Feere has put together 10 questions about other immigration matters that conscientious debate moderators (sic) could pick from. Questions 1-5 are here and 6-10 are here. Perhaps the most important, with implications not just for the federal immigration program but for constitutional government in general, is “In your opinion, is there any limit to what a president can do on immigration, and if so, where is that line drawn? Does a president have legal authority to admit into the country anyone he or she wants,without congressional authority?”
