Explainer: Federal law that protects voters from last-minute removal is at the center of Trump’s anti-voting war

For voting rights advocates, this coordinated attack on the landmark federal protection is not abstract.

“Much like with its mass deportation agenda, the Department of Justice is asking for something unprecedented: the power to remove voters from the rolls based solely on suspicion that they are not citizens. Never before has the federal government claimed such authority over our elections, threatening the longstanding balance between state and federal responsibilities,” Hector Sanchez Barba, President and CEO of Mi Familia Vota, said after the Supreme Court agreed to hear the case. “We have already seen eligible citizens wrongly removed from voter rolls and forced through burdensome bureaucratic hurdles to restore their voting rights. That is not election integrity — it’s disenfranchisement.”

The fight over the NVRA’s quiet period goes beyond one state law or lawsuit. It is a fight over whether eligible voters will have meaningful protection from being wrongly removed from the rolls at the moment when the consequences are hardest to undo.

The National Voter Registration Act, often called the “Motor Voter” law, was enacted in 1993 to boost voter registration nationwide by making it more accessible and to protect eligible voters from being wrongly pushed off the rolls.

Under the law, states must complete any program meant to systematically remove ineligible voters from the official voter rolls no later than 90 days before a primary or general election for federal office. In other words, states cannot wait until the final stretch before an election to launch broad purge programs that could remove eligible voters by mistake.

That rule exists because voter purges are different from ordinary voter roll maintenance. When a voter is wrongly removed months before an election, there may still be time to discover the error, correct the record and cast a ballot. When that same mistake happens weeks or even days before Election Day, the damage can become impossible to undo.

“The 90-day quiet period exists because elections require stability, not chaos, in the run-up to Election Day. Congress recognized that if eligible voters are swept up in a large removal program shortly before an election, many won’t have enough time to discover the mistake and get it corrected,” Pamela Smith, president and CEO of the pro-voting nonprofit Verified Voting, told Democracy Docket. “Removing the 90-day buffer takes away the only structural safeguard between a bad data match and eligible voters’ ability to participate.”

It does not stop election officials from processing new registrations, correcting clerical errors or making routine updates. And it also does not prevent removals when a voter themselves asks to be removed, when a voter has died, when a voter is disqualified under state law because of a criminal conviction or mental incapacity, or when the state follows the NVRA’s procedures for confirming that a voter moved.

But those few exceptions do not give states a blank check to run mass purge programs at the last minute.

“That doesn’t mean voter registration lists stop being maintained. Election officials update them year-round, and individualized changes still happen during the quiet period — whether that’s processing a voter’s own request to cancel their registration, recording a death, or making other routine corrections permitted under state and federal law,” Smith said. “What the quiet period restricts is a systematic effort to remove a broad class of voters based on shared criteria.”

A truly individualized removal is based on specific, reliable information about a particular voter. A systematic purge uses a broader process — often a database match, list or set of criteria — to flag entire groups of voters for removal.
