How many members are in the United States Senate?

The United States Senate is composed of 100 members, which aligns with the principle that each state is represented by two senators, regardless of its population size. This structure ensures equal representation for all states in the Senate, making it distinct from the House of Representatives, where representation is based on population. This equal representation was a compromise during the Constitutional Convention to balance the interests of both populous and less populous states. Hence, with 50 states in the U.S., multiplying 50 by 2 results in 100 senators, affirming that the correct answer is indeed 100 members.
