American cities face a host of problems but one common claim from conservatives is that the biggest issue is that all of them are run by Democrats:

The rapid growth of urban areas, increased population density, and a massive influx of immigrants—accompanying the explosion of manufacturing and commerce during the Gilded Age—hastened the rise of municipal political machines (such as Tammany Hall in New York City), official corruption, labor unrest, and the demographic diversity that continues to this day. Even though Americans’ standard of living generally improved during industrialization (people moved to the cities for a reason), the Progressive movement was in significant part a response to America’s nascent urban problems.

Progressivism is a legacy that endures, as we know, and for good or ill, urbanization has profoundly affected the American experience. Members of ethnic minorities disproportionately reside in U.S. cities, and their local governments are disproportionately (in fact more or less exclusively) in the hands of the Democratic Party. Cities expend substantial taxpayer resources to try to address poverty, crime, air pollution, congestion, substandard housing, homelessness, and the education of non-English speaking students, all of which are not as prevalent in suburban and rural areas.

Cities tend to have large numbers of unionized public employees, high (and rising) taxes and debt (including unfunded pension liabilities), and intrusive regulations. For a variety of reasons, urban residents favor liberal policies—and elect liberals to office—to a greater degree than suburban and rural voters. Some major American cities, such as Detroit, have become dysfunctional fiefdoms, forced into bankruptcy…

Cities present different challenges than they did a century ago, but the current problems are no less dire. Costly and ineffective public education systems, massively under-funded public employee pension plans, law-enforcement failures, high taxes, and uncontrolled spending imperil the security and solvency of America’s cities. Unless these problems are promptly addressed by responsible state reforms, more urban residents will face the tragic plight of Detroit, Chicago, Baltimore, and San Bernardino.

Two quick thoughts:

1. It would be interesting to see a recent example where more conservative policies helped a large city. Perhaps it is simply hard to find a case from today with most big cities having Democrat mayors. Is the historical record kinder? I recently read about “Big Bill” Thompson who was the last Republican mayor of Chicago, leaving office in 1931. He had all sorts of problems and Wikipedia sums up: “He ranks among the most unethical mayors in American history.” Maybe we could look to Rudy Giuliani in New York City who is often credited for helping reduce crime in the city (due to applying broken windows theory) and for strong leadership after the September 11th attacks. But, some of his legacy has been questioned as crime rates dropped in numerous other major cities and such policies may have come at a cost. All together, it is easy for one party to blame the other but why not have a discussion of exactly how Republicans have actually helped cities in recent years?
2. Cities are complex places which is why they started drawing so much attention from social scientists and others in the 1800s. Having a change in political party of leadership won’t automatically solve issues: how do we tackle neighborhoods that have now been poor for several generations? How about income inequality? Development and economic opportunities throughout big cities and not just in wealthy areas? The presence and activity of gangs? Providing affordable housing? Avoiding police brutality? Maintaining and upgrading critical infrastructure? Again, it is easy to blame one party but these are not easy issues to address – there is a level of complexity that would prove difficult for a mayor of any party.
