legislative branch, or Congress, includes another lawmaking body
called the Senate. Voters elect two senators from each state, regardless
of population size. There is equal representation from each state
in the Senate. It doesn't matter if the state is big or small, densely
or sparsely populated, or where it is located. Senators are elected
every 6 years. The elections are staggered so that both senators
from a state are not elected at the same time.
Only the Senate
can approve or reject treaties and presidential nominations for
states the qualifications for being a senator. To be a senator a
person must be at least 30 years old, a U.S. citizen for at least
9 years, and have fulfilled the requirements for residency in the
state that person wishes to represent.
