The Constitution entrenches the rule that decisions are made in the Senate by majority voting; it is not open to the Senate, as it is to houses of some other legislatures, to alter the principle of majority voting and to adopt some other method of making decisions by changing its internal rules of procedure. This entrenchment of the principle of majority voting is in accord with the theory of the geographically distributed majority underlying the composition of the Senate.1
