Watson v. Republican National Committee: When Election Day Is Not Election Day

The Supreme Court let Mississippi's law allowing absentee ballots to arrive after Election Day stand on very narrow grounds in a case that goes to the heart of election integrity.

The core question: Do federal election-day statutes require all absentee ballots to be received by Election Day?

RTW’s read: The Supreme Court held that the federal election-day statutes govern when ballots must be cast, not when state election officials must receive them. By ruling on such narrow grounds, the Court may have set the stage for election season chaos.

BACKGROUND

In 2024, the Mississippi Republican Party, the Republican National Committee, the Libertarian Party of Mississippi and others filed lawsuits challenging a state statute allowing absentee ballots postmarked by Election Day to be counted if received within five days. The trial court upheld the state law, but the Fifth Circuit reversed, holding that federal election-day statutes require ballots to be submitted and received by Election Day. The Supreme Court granted certiorari and reversed.

WHY THE COURT TOOK THIS CASE

The last several election cycles have been rife with controversy and claims of voter fraud and irregularities. In reality, this is nothing new. The 2026 midterm elections are already shaping up to be contentious and the Court has already ruled on several election-related issues as states navigate concerns over election integrity, procedures, and vulnerabilities to fraud. These questions could not remain unresolved heading into the election season.

WHAT’S AT STAKE

The Constitution provides that state legislatures are free to prescribe “Times, Places and Manner of holding Elections of Senators and Representatives.” The Supreme Court has held, however, that Congress may override most of those choices. As long as they comply with federal election-day laws and the Constitution’s scant requirements, each state is free to develop its own system for administering federal elections. In the 19th century, when Congress imposed few requirements, the result was chaos. Both the Court’s majority and dissenting opinions recount this history.

An unusual majority coalition of two conservative and and three progressive justices produced a narrowly drawn statutory ruling that “is not about the Constitution.” ” It does not address the general legality of absentee voting and leaves important questions about mailed ballots unresolved, providing little guidance on issues the dissenting justices raise.

THE DECISION

The Supreme Court ruled that “federal law dictates when ballots must be cast, [and] state law dictates when they must be received.” As a result, no federal law preempts Mississippi’s ballot receipt deadline, so the challenge to the law on federal statutory grounds fails. Therefore, ballots postmarked by Election Day and received within five days are valid and may be counted.

“It is undeniable that a prohibition on counting late-arriving ballots would provide an additional hurdle for bad actors seeking to stuff ballot boxes when early election results suggest a tight race.” — Justice Samuel Alito, dissenting

CONCURENCE AND DISSENT

Dissent: Justice Alito argued that the majority opinion is “inconsistent with the terms of the election-day statutes, contemporary election-law principles, two centuries of historical practice, and the case law on the question presented.” In his view, a vote is not cast until a ballot is completed and delivered to the appropriate official. Because a late-arriving ballot has not been delivered on Election Day, it should not be counted.

THE PRECEDENT

Even if the majority opinion correctly interprets and applies federal law, it provides no guidance for states and courts on whether a deadline exists for late-arriving ballots. The dissent warns that allowing ballots to arrive days or weeks after Election Day could leave elections perpetually open, prolonging uncertainty over the results. The majority is right that Congress could resolve many of these questions. But the dissent argues that Congress has already settled these issues through the election-day statutes when properly interpreted and applied.

WHAT COMES NEXT

The coming months will likely see even more litigation over state election procedures. These lawsuits will come from both the right and the left. But Congress will need to settle quite a few of these issues in the future because litigation cannot not and should not settle all of them.

THE BOTTOM LINE

The number of Americans losing confidence in elections is growing, in part because they recognize what a bipartisan group of experts led by President Jimmy Carter and former Secretary of State James Baker is true: mail in ballots pose the greatest threat of voter fraud in modern elections. The Court had more other paths to a just result without destabilizing the electoral process. Congress must act to restore confidence among the American people that our elections are free, fair, and secure.
