Why does america have exactly 100 senators? - america decided on a nice even number - people like the number 100 - 100 is a number that is large but simple to work with - there are 2 senators from each state, 50x2=100

A: There are two senators from every state (50 x 2 = 100).

It ultimately stems from a compromise on the New Jersey Plan and the Virginia Plan (the two plans devised by the Northern/small states and the Southern/larger states as possible structures for the Legislative branch). The Connecticut Compromise established a bicameral legislature which included elements of both plans to satisfy both parties. We have the House of Reps where the # of a state’s representatives are determined by population as desired by proponents of the Virginia plan, and the Senate where each state had an equal amount of representatives and therefore an equal amount of votes (as desired by New Jersey and other small states to ensure the larger states would not always get their way, and that they would have a voice in government).
