Why It Matters
The outcome of a major federal election law case could reshape how states manage voter rolls before federal elections nationwide. If the U.S. Supreme Court sides with the Trump administration and the Republican National Committee, states would gain broader authority to remove voters from registration lists in the weeks immediately preceding an election — a change with potential implications for the 2028 presidential race.
What Happened
The U.S. Department of Justice formally asked the Supreme Court on Tuesday to take up a legal dispute pitting the Republican National Committee against Democratic Party organizations and voting rights groups over several voting restrictions in Arizona.
At the center of the case is whether Arizona’s proof-of-citizenship requirements for voter registration — and the state’s use of a federal database to screen voter rolls for possible noncitizens — conflict with the National Voter Registration Act of 1993. That federal law prohibits systematic purges of voter rolls within 90 days of a federal election.
The U.S. Ninth Circuit Court of Appeals previously ruled that Arizona’s law violates the NVRA. The Justice Department is now asking the Supreme Court to reverse that ruling, arguing the appeals court’s decision strips states of flexibility they are entitled to when enforcing their own voter qualification standards.
Arizona currently requires residents to submit documentation — such as a passport or birth certificate — to vote in state elections. Those who use a federal registration form without providing such documents are limited to voting in federal elections only. State law also directs election officials to run those federal-only registrants through a Department of Homeland Security verification system designed to flag potential noncitizens.
By the Numbers
- 90 days: The window before a federal election during which the NVRA restricts systematic voter roll removals.
- 1,600+: Voter registrations canceled in Virginia during a 2024 pre-election purge ordered by then-Governor Glenn Youngkin; documented cases showed U.S. citizens were among those removed.
- 1993: Year Congress enacted the National Voter Registration Act, which governs registration procedures and pre-election removal limits.
- 2028: The earliest presidential election that could be directly affected by a Supreme Court ruling in the case.
The Arguments
RNC Chairman Joe Gruters framed the case in straightforward terms. “Federal law is clear: only U.S. citizens have the right to vote in American elections,” he said in a public statement.
Opponents of the Arizona law, including the Democratic National Committee and the Arizona Democratic Party, counter that Congress specifically designed the 90-day restriction to give eligible voters sufficient time to contest erroneous removals before casting ballots. “States cannot circumvent the limits on systematic removals that Congress put in place,” they argued in a brief filed the same day.
A key concern involves the SAVE system — Systematic Alien Verification for Entitlements — a Department of Homeland Security program originally built to verify individual eligibility for government benefits. The Trump administration has expanded its capabilities, enabling it to cross-check millions of names simultaneously against federal citizenship records. Several Republican-led states have already uploaded their voter rolls to SAVE in search of potential noncitizens.
Critics warn the system generates errors. Justin Levitt, a law professor at Loyola Marymount University who previously advised the Biden White House on voting policy, noted that matching large databases always produces mistakes. “If you execute this systemic list maintenance two days before the election, those mistakes are going to keep eligible voters from voting,” Levitt said in public remarks.
Zoom Out
The Arizona case arrives as election administration has become a major national flashpoint. The SAVE Act — part of President Trump’s broader elections legislation — would require proof of citizenship for federal voter registration, but the measure has stalled in Congress. A favorable Supreme Court ruling in the Arizona dispute could effectively advance some of those same policy goals through the courts rather than legislation. The issue is also playing out in state-level elections across the country, where voter eligibility and election integrity rules continue to shape primary and general election dynamics.
What’s Next
The Supreme Court has not yet agreed to hear the case. If the justices accept it, a ruling would likely arrive before the 2028 presidential election. The court’s decision could set a national precedent on how broadly states may use federal databases to screen voter rolls and how close to an election such reviews may take place.
