Voter turnout in the United States presidential elections
Recent decades have seen increasing concern over the fact that youth voting turnout is consistently lower than turnout among older generations. Several programs to increase the rates of voting among young people—such as MTV's "Rock the Vote" (founded in 1990) and the "Vote or Die" initiative (starting in 2012)—may have marginally increased turnouts of those between the ages of 18 and 25 to vote. However, the "Stanford Social Innovation Review" found no evidence of a decline in youth voter turnout. In fact, they argue that "Millennials are turning out at similar rates to the previous two generations when they face their first elections."
Jennings Randolph
Randolph was best known for sponsoring eleven times an amendment to the Constitution that would grant citizens aged between 18 and 21 the right to vote. He first introduced the amendment in 1942, arguing that young soldiers fighting in World War II should be able to vote. In 1970 amendments to the Voting Rights Act lowered the voting age to 18 in both local and national elections. After the Supreme Court found in "Oregon v. Mitchell" that Congress only had the power to lower the voting age to 18 for national elections, and no power to lower it for state elections, Randolph was among the Senators who reintroduced the amendment. It was ratified by three-fourths of the states in 1971 as the Twenty-Sixth Amendment, 107 days after it was approved by Congress.
