State and local policy. Localities can expand voting and enhance civic engagement for all citizens by joining the practice of several nations and other jurisdictions in enfranchising otherwise-eligible voters when they turn 16.
State and political party policy. If a voter will be eligible to vote in the general election, they should be able to vote in the primary or caucus that will nominate candidates to be on their ballots. An increasing number of states and political parties have therefore extended voting rights in primaries and caucuses to 17-year-olds who will be 18 by the date of the next general election.
