In 1971, the Twenty-sixth Amendment set the legal voting age at 18 for both US federal and state elections.
Voter registration is open to people 18 years or older, citizens, and have an address. The purpose of it is to ensure the voting process is legal and that people who don't fit â¦ the guidelines/laws allowing them to vote don't vote. When you vote you sign a book next to your name and show ID to prove you are who you are. This also prevents someone from voter fraud or voting twice.
