<P> The number of voting seats in the House of Representatives is currently set at 435, where it has been since 1913--except for a temporary (1959--1962) increase to 437 after Alaska and Hawaii were admitted into the Union . The total number of state members is capped by the Reapportionment Act of 1929 . </P> <P> Because the size of a state's total congressional delegation determines the size of its representation in the U.S. Electoral College, congressional apportionment also affects the U.S. presidential election process as well . </P> <P> Though the actual reapportionment will normally occur in respect of a decennial census, the law that governs the total number of representatives and the method of apportionment to be carried into force at that time can be created prior to the census . </P> <P> The decennial apportionment also determines the size of each state's representation in the U.S. Electoral College . Under Article II, Section 1, Clause 2 of the U.S. Constitution, any state's number of electors equals the size of its total congressional delegation (House and Senate seats). </P>
