is there a difference between state senators and us senators
Classes of United States Senators A senator's description as junior or senior senator is not related to his or her class. Rather, a state's senior U.S. senator is the one with the greater seniority in the Senate. This is mostly based on length of service.
United States Congress The members of the House of Representatives serve two-year terms representing the people of a single constituency, known as a "district". Congressional districts are apportioned to states by population using the United States Census results, provided that each state has at least one congressional representative. 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.
