How often is the senate elections held?
A senator holds his/her seat for six years, but elections are held every two years. This process divides the Senate into three groups, resulting in the reelection of one of the three groups (one-third of the Senate) at a time. By doing so, the Senate is sure to maintain experienced senators as new ones (aka “Freshmen Senators”) replace the old ones. I believe the possiblity of replacing all seasoned Senators with totally new ones was a concern to the Founders, a possibility that may have been more feasible when the country started out with only 13 states (26 senators).
