The main purpose of this legislative proposal is to amend the U.S. Constitution to ensure that only U.S. citizens are allowed to vote in elections at all levels, including federal, state, and local elections. The objective is to clarify and reinforce voting rights by explicitly stating that non-citizens cannot participate in the electoral process. Key provisions of this amendment include a clear statement that individuals must be U.S. citizens to vote in any public office elections or on ballot initiatives and referendums.
