who were the bosses of the senate?

Vice president

and The Senate Majority leader...

To determine who were the bosses of the Senate, you would need to look into the leadership positions in the U.S. Senate. Throughout history, the term "bosses" is not commonly used to describe Senate leadership, but rather terms like "majority leader" and "minority leader" are more appropriate.

In the United States Senate, the majority and minority leaders play crucial roles in shaping legislative agendas and exerting influence over their respective party members. The majority leader is typically the most powerful member of the majority party, while the minority leader is the highest-ranking member of the minority party.

As of my last knowledge update in January 2022, the majority leader in the U.S. Senate is Senator Chuck Schumer, a Democrat from New York. The minority leader is Senator Mitch McConnell, a Republican from Kentucky. However, please note that leadership positions in the Senate can change over time as political dynamics evolve and leadership elections occur.

To find the most up-to-date information on the current leaders of the U.S. Senate, I recommend checking reliable news sources, official government websites, or the Senate's official website.
