Absentee and Mail Voter Protection Act

Maddy summaryThis bill, known as the Absentee and Mail Voter Protection Act, aims to overturn a specific executive order by repealing it and prohibiting the use of federal funds to implement similar directives in the future. It directly affects the United States Postal Service, various federal agencies, and state election officials by restricting their ability to regulate mail-in ballots or create national citizenship lists for voting purposes. Key provisions ban federal agencies from sharing voter registration data, compel the Postal Service to continue delivering state-issued mail ballots without interference, and forbid the use of taxpayer money to enforce rules that would require states to adopt specific citizenship verification methods. The legislation seeks to preserve the current system where states manage their own election administration while the Postal Service delivers ballots, citing historical precedents and the high volume of mail-in voting used by Americans.
