Supreme Court case could have major affect on 2026 midterms

The U.S. Supreme Court has agree to take up a case that could have an effect on the 2026 midterm elections.

The case, Watson v. Republican National Committee, centers around a Mississippi law that allows mail-in ballots to be counted up to five days after an election as long as they are postmarked by Election Day. The Mississippi law was enacted in 2020 due to the COVID-19 pandemic.

Fifteen other states and the District of Columbia have similar laws that allow domestic mail-in ballots to be received after Election Day, as long as the ballot is postmarked by the date of an election. In Illinois, mail-in ballots can be received up to 14 days after Election Day.

The nation’s highest court will decide whether to uphold a ruling from the Fifth U.S. Circuit Court of Appeals that said ballots must be received by Election Day to be counted.

Jason Snead, executive director of the Honest Elections Project, celebrated the court’s decision to take up the mail-in ballot challenge. He said the court’s decision is especially important because it will set a precedent for election law going into the 2026 midterms.

“The Supreme Court now has the chance to set the record straight: Federal law clearly says that ballots must be received by Election Day,” Snead told the Center Square. “Despite this, some states continue to allow absentee ballots to pour in days or even weeks late.”

“This case gives the Supreme Court the chance to resolve that question once and for all,” Snead said.

Ken Martin, chair of the Democratic National Committee, said the case is an attempt to restrict voting rights in states that offer delayed mail-in ballot deadlines.

“The DNC will fight like hell in this case for the rights of Mississippians and every other citizen to make sure their voices are heard and their votes are counted,” Martin said.

Lawyers for the Republican National Committee argued that federal law sets the Tuesday after the first Monday in November as Election Day.

Nineteen states and the District of Columbia filed a brief to the Supreme Court that argued states should have the ability to set rules over the receipt of ballots. The states said mail-in ballot deadlines give voters a greater opportunity to cast their ballots.

“States have the constitutional authority to make individualized judgments on how best to receive and count votes in federal elections,” representatives for the state wrote.
