Trump's 2028 Mail-In Voting Push Faces Legal Hurdles After Supreme Court Ruling

President Donald Trump's efforts to establish new federal rules for mail-in ballots ahead of the 2028 presidential election are facing significant legal uncertainty, following a Supreme Court decision that declined to lift a preliminary injunction blocking the rules' implementation before the upcoming midterm elections. The core of the legal debate centers on the balance of authority between the executive branch's ability to regulate the Postal Service and the states' autonomy in administering elections.

Trump issued an executive order in March directing the Postal Service to implement new regulations for federal mail ballots. These proposed rules included standardized ballot envelopes designated as 'Official Election Mail' and unique machine-readable barcodes. Crucially, the order would have empowered the Postal Service to reject ballots that did not meet these new standards or belonged to individuals not appearing on state-provided lists of eligible mail voters. This move, intended to enhance ballot integrity and streamline mail processing, has been met with both support and opposition.

The Supreme Court, in a 7-2 decision on September 14, upheld the injunction that prevents these new rules from taking effect for the November midterm elections. Justices Clarence Thomas and Samuel Alito dissented, while Justice Brett Kavanaugh voted to uphold the injunction. Kavanaugh noted that while the Postal Service might possess the statutory authority to enact such regulations, their implementation so close to an election could violate federal law.

Legal experts offer diverging interpretations of the ruling's long-term impact. Michael Morley, a law professor at Florida State University, suggests that the Supreme Court's view of the executive order will be pivotal. If the Court perceives the order primarily as an attempt by the President to regulate federal elections, it is likely to be invalidated, as the President lacks inherent constitutional authority over election administration, and Congress has not broadly delegated such power. However, Morley posits that if the Court views the rules as primarily administrative measures aimed at improving Postal Service efficiency and mail integrity, they might be upheld.

Stephen Richer, a legal fellow at the Cato Institute, believes the ruling indicates that a majority of justices may lean towards invalidating the order on its merits, arguing that the Constitution grants broad authority over election administration to Congress and the states, not the President. Richer, a former Republican election official in Arizona, stated, "The Constitution doesn't vest authority to regulate elections to the president and I think that they would say that this effectively dictates how elections can be run."

Conversely, Chad Mizelle, senior legal fellow at the America First Policy Institute, argues that Justice Kavanaugh's concurring opinion suggests the ruling was based on timing rather than the underlying law. "He concluded there simply wasn't enough time left before the midterms to implement the rule responsibly. That's a timing question, not a ruling on the underlying law," Mizelle stated. Mizelle, who previously served as chief of staff at the Justice Department, emphasized that the proposed regulations concern basic chain-of-custody standards, such as verified voter lists and tamper-resistant envelopes, which he believes are essential for ballot mail.

Following the Supreme Court's decision, Trump characterized the injunction as a significant setback for Republicans and a victory for those who might engage in mail-in ballot fraud. "Republicans just got another bad decision from the United States Supreme Court, one that the Court System took forever to give, and then blamed it, in part, on no time left to implement a solution to our totally CORRUPT and out of control Mail-In voting ‘disaster,’" he wrote on Truth Social. While acknowledging isolated cases of election fraud, the article notes that these do not indicate widespread issues with U.S. mail voting.

Ilya Shapiro, a senior fellow at the Manhattan Institute, described the legal question as complex and not a "slam dunk." He noted that the central issue is not the merits of mail voting itself, but rather the determination of which entity—state, Congress, or a federal agency—holds the authority to set the rules for it.
