Meanwhile, statewide campaigns to lower voting age in Missouri, Rhode Island, and Oregon are growing and have garnered support from both Republicans and Democrats. Less than six decades ago, in 1971, the 26th Amendment to the Constitution lowered the voting age from 21 to 18. One 2019 poll from The Hill/HarrisX found that 75% of registered voters opposed letting 17-year-olds vote, and 84% opposed voting rights for 16-year-olds. Studies on adolescent brain development suggest that fears of 16-year-olds not having the decision-making power to cast a vote are unfounded. Students were driven to organize around lowering the voting age because of issues they experienced and that adults seemed to overlook.
