twenty-one years of age in such State." The Fifteenth Amendment prohibits the denial of the right to vote based on race, color, or previous condition of servitude. The Nineteenth Amendment prohibits the denial of the right to vote based on sex. The Twenty-fourth Amendment prohibits the revocation of voting rights due to the non-payment of a poll tax. The Twenty-sixth Amendment prohibits the denial of the right of US citizens, eighteen years of age or older, to vote on account of age. Moreover, since the Supreme Court has recognized voting as a fundamental right, the Equal Protection Clause places very tight limitations (albeit with uncertain limits) on the states' ability to define voter qualifications; it is fair to say that qualifications beyond citizenship, residency, and age are usually questionable. In the 1960s, the Supreme Court started to view voting as a fundamental right covered by the Equal Protection Clause of the Fourteenth Amendment. In a dissenting opinion of a 1964 Supreme Court case involving reapportionment in the Alabama state legislature, Associate Justice John Marshall Harlan II included Minor v. Happersett (an 1875 case which allowed states to deny women the right to vote) in a list of past decisions about voting and apportionment which were no longer being followed. In Oregon v. Mitchell (1970), the Supreme Court held that the Qualifications clause did not prevent Congress from overriding state-imposed minimum age restrictions for voters in Congressional elections. Since clause 3 provides that Members of the House of Representatives are apportioned state-by-state and that each state is guaranteed at least one Representative, exact population equality between all districts is not guaranteed and, in fact, is currently impossible, because while the size of the House of Representatives is fixed at 435, several states had less than 1/435 of the national population at the time of the last reapportionment in 2020. However, the Supreme Court has interpreted the provision of Clause One that Representatives shall be elected "by the People" to mean that, in those states with more than one member of the House of Representatives, each congressional election district within the state must have nearly identical populations. Clause 2: Qualifications of Members The Constitution provides three requirements for Representatives: A Representative must be at least 25 years old, must be an inhabitant of the state in which he or she is elected, and must have been a citizen of the United States
