Answer:
A political machine is an unofficial political organization that ran big cities.
Step-by-step 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.
The political machine works unofficially through the awarding of offices, behind-the-scenes control and long-standing political ties within the framework of representative democracy.
