A National Emergency: Subversion of the Constitutional Order
First things, there are situations that do rise to the level of a national emergency. Usually, they involve an act of war or a major natural disaster. Pearl Harbor, 9–11, and even the current freeze in the center of the country qualify as one. People are dying from the cold, in particular, the poor and the homeless who are not able to remain warm. This is the kind of situation that could use federal intervention. In fact, it could use an emergency declaration, and the mobilization of both state (they are happening) and federal assets.
