According to Axios, President Donald Trump's push to restrict mail-in voting through the U.S. Postal Service would require USPS to review outgoing mail-ballot envelopes for compliance with federal requirements before accepting them, while election officials would have to use a new Federal Ballot Mail Portal to submit personal information about voters receiving mail ballots. Voting rights groups say the proposal could give the federal government control over voting data and state-run elections, and could scramble the 2026 midterms by forcing local and state officials to adopt an untested federal system on short notice. The League of Women Voters of Massachusetts filed a motion Saturday to enforce a federal court order blocking USPS from implementing the rules, and the administration has asked the Supreme Court to intervene. Massachusetts officials have already spent more than $3 million on ballot envelopes that could become unusable.
