Democratic states are suing the Postal Service to block President Trump’s executive order tightening mail-in voting rules, revealing their determination to preserve a system ripe for abuse. This partisan litigation matters because it directly undermines efforts to verify ballots and prevent fraud that dilutes the votes of law-abiding citizens. The Constitution grants the federal government clear authority over the mails and the integrity of federal elections, not a license for states to commandeer executive agencies for their political ends. Limited government means protecting the people’s franchise from manipulation, not expanding opportunities for unchecked mail ballots that evade scrutiny. Federalism does not empower activist attorneys general to override national standards for election security. Voters deserve a system that counts only lawful ballots, and these lawsuits expose exactly why such reforms remain essential.
