Most Americans have never heard of the National Response Coordination Center, but they’re lucky it exists on days of lethal winds and flood tides. The center is the war room of the Federal Emergency Management Agency, where officials gather to decide where rescuers should go, where drinking water should be shipped, and how to assist hospitals that have to evacuate.

Disaster coordination is one of the most vital functions of “big government,” which is why Mitt Romney wants to eliminate it. At a Republican primary debate last year, Mr. Romney was asked whether emergency management was a function that should be returned to the states. He not only agreed, he went further.
