Each state, regardless of population or size, has two senators. Currently, there are 100 senators representing the 50 states. Each senator is elected at-large in their state for a six-year term, with terms staggered, so every two years approximately one-third of the Senate is up for election.
As each new state was added to the union over time, two more senators were added to the Senate. In 1959, the present body of 100 senators was complete, with two senators representing each of the 50 states. Each senator serves a six-year term with the chance of reelection at the end of this period.
