Applying a regression discontinuity design to deal with the endogeneity of the mayor's party, we find that party labels do not affect the size of government, the allocation of spending or crime rates, even though there is a large political advantage to incumbency in terms of the probability of winning the next election. The absence of a strong partisan impact on policy in American cities, which is in stark contrast to results at the state and federal levels of government, appears due to certain features of the urban environment associated with Tiebout sorting. In particular, there is a relatively high degree of household homogeneity at the local level that appears to provide the proper incentives for local politicians to be able to credibly commit to moderation and discourages strategic extremism.
