Our astute political readership is well aware that the United States Senate has been divided into three classes since the beginning of the Constitutional Republic. That’s because, with a six-year term for each senator, only one-third of the Senate is elected every two years. Senators were elected by the state legislatures until the ratification of the 17th Amendment in 1913, of course, but the classes were maintained with the electoral reform, and as new states were added to the Union, the principle of “one-third every two years” has been continuous. While the U.S. House of Representatives is (theoretically) “refreshed” in its entirety by the People at each election, the Senate is much more stable, since two-thirds of the Senate membership is immune from popular uprising in any given election. Passions are given a chance to cool, or to reconstitute, before the next election rolls around.
