A political machine is an unofficial political organization that ran big cities.

Explanation:

A political machine is a system of unequal personal dependencies in political apparatuses between influential people and their clients.  In other words, it is a system that controls the political organization of a given territory, exercised through the political power of certain members of the public administration.
