Slate magazine has an interesting story about how the United States has not elected a president with previous experience as a city mayor in almost 100 years. Republican Calvin Coolidge was the last, serving as president from 1923 to 1929 after being mayor of Northampton, Massachusetts from 1910 to 1912. Several politicians who are or were mayors are currently vying for the Democratic nomination. It will be difficult for them to succeed, as “the sphere mayors operate in is largely subservient to state and federal government. Power resides with state and federal officials, who tend to take credit and deflect responsibility when it comes to urban affairs. A governor might score points for a tax cut, for example, but leave it to a mayor to figure out how to maintain after-school programs with less revenue.” Current national trends, however, are producing questions about cities and/or issues driven by urban life. “We may not get a president who ran one of the country’s cities, but at least, for a change, we’ll get to talk about them.” Indeed!
