Written constitutions matter little in Latin American countries run by strutting ex-colonels and widows of populist demagogues. In these banana republics, the caudillo exercises both executive and legislative powers. Laws are not written by legislatures, but emanate from the strongman’s pen.

The U.S. would be heading further in this direction if Hillary Clinton becomes president. This might sound outlandish, but consider that President Obama has repeatedly taken unconstitutional actions and sabotaged the separation of powers. “What the president is suggesting,” Georgetown law professor Jonathan Turley said regarding Mr. Obama’s executive order on immigration, “is tearing at the very fabric of the Constitution.”

A Clinton presidency would ratify the new post-Constitutional order. Mrs. Clinton explicitly says that she will disregard the separation of powers and assume the legislative branch’s prerogative.

Her campaign website promises that President Clinton will “tighten the gun show and Internet sales loophole if Congress won’t.” She will “take administrative action to require that any person attempting to sell a significant number of guns be deemed ‘in the business’ of selling firearms.”
