Final answer:
Political bosses exercised control over local political parties through patronage, corruption, and mobilization of voters.
Step-by-step explanation:
In the history of the United States, political bosses exercised great control over local political parties during the late 19th and early 20th centuries. These political bosses were usually leaders of political machines, such as Tammany Hall in New York City. They used tactics like patronage, bribery, and fraud to maintain their power and control over local political parties.
For example, Boss Tweed, the leader of Tammany Hall, had significant control over New York City's Democratic Party. He used his influence to secure government contracts and jobs for his loyal supporters, while also benefiting financially from these deals. Tweed's control over the Democratic Party allowed him to maintain power and expand his influence in local politics.
Overall, the political bosses exercised great control over local political parties through their manipulation of patronage, corruption, and their ability to mobilize voters in their favor.
