Clean Voter Rolls Are a Legal Duty, What the 1993 Motor Voter Law Requires

A list that nobody ever cleans is not a list. It is an attic. Things go in, nothing comes out, and after a few decades you are holding the names of people who moved to Phoenix in 1998, people who married and changed their names twice, and people who have gone on to their reward and are, as far as the county is concerned, still on the books and still on the mailing list. Ask anyone who has ever tried to get off a catalog's mailing list how efficient that process is.

Now, here is the part that surprises people. Keeping that list clean is not merely a good idea. It is a legal duty, imposed by a federal statute that most Americans know only as the law that lets you register at the DMV. The same law that made it easier to get on the rolls also told the states, in plain words, to make a reasonable effort to take the right people off. Let me walk you through what it says, because the two halves belong together.

The National Voter Registration Act of 1993

President Clinton signed the National Voter Registration Act on May 20, 1993, and its main provisions took effect in 1995. Everybody calls it the Motor Voter law, because its signature feature is that anyone applying for or renewing a driver's license must be offered a chance to register to vote at the same time. It also requires registration opportunities at public assistance offices and by mail.

That half of the law was about access. The other half, tucked into Section 8, is about list maintenance. It is codified today at 52 U.S.C. 20507. Here is the sentence that matters. It requires each state to conduct "a general program that makes a reasonable effort to remove the names of ineligible voters from the official lists of eligible voters by reason of" the death of the registrant, or a change in the registrant's residence.

Look at the structure. The law says shall. It does not say a state may maintain its rolls if it feels like it. It says the state must make a reasonable effort to remove two categories of people: the dead and the departed. And the same Section 8 sets the rules for how, which is where the interesting detail lives.

What Section 8 forbids

First, the limits, because they are as important as the duty. A state may not remove a voter simply because the voter did not vote. The statute says so directly: a registrant cannot be removed by reason of failing to vote. That surprises a lot of people on both sides. Failure to vote can be the start of a process, but it cannot be the reason for removal.

The statute also bars removal based on a change of residence unless one of two things happens. Either the voter confirms in writing that he or she has moved outside the jurisdiction, or the state sends a notice and the voter does not respond and does not vote or appear to vote in the next two federal general elections. That is the notice-and-wait rule, and it is the heart of the process.

Here is how it works in practice, in steps.

1. The state finds a reason to think a registrant has moved. That might be a change-of-address record from the postal service, or no activity in a given period.
2. The state sends a notice, usually a postage-paid return card, asking the voter to confirm that he or she still lives at the address.
3. The voter has the chance to respond. If the voter confirms, the registration stays. If the voter updates the address within the jurisdiction, the record is corrected.
4. If the voter does not respond, the registration moves into an "inactive" status. The voter is not removed. He can still vote, usually by affirming his address at the polling place.
5. After the notice, if the voter does not vote or appear to vote in the next two federal general elections, the state may remove the name.

That is a long runway. It means that a name leaves the rolls only after a notice, a chance to answer and roughly two federal election cycles of silence. If you were designing a process to be fair to the voter, it would look a lot like that. And if you were designing one to protect the voter and keep the list accurate, you could not do much better.

The 90-day quiet period

Section 8 contains another rule that conservatives and liberals alike should know. A state must complete any systematic program to remove ineligible names no later than 90 days before a federal election. That is the quiet period, and the logic is simple: mass list maintenance close to an election risks sweeping in eligible voters by mistake, with no time to fix the error. So the statute says to finish the cleaning early.

The quiet period has exceptions. It does not apply to removals at the voter's own request, removals because of a criminal conviction or mental incapacity where state law provides for them, or removals because the registrant has died. A state can take the dead off the rolls in the weeks before an election. It simply cannot run a sweeping residence-based purge in that window.

Here is the practical lesson for anyone who cares about clean rolls: the time to push is in the off year, well before the election, when the process can run at a careful pace and errors can be fixed. A state that waits until September of an election year has chosen the worst time.

Husted v. A. Philip Randolph Institute

The law's text has been tested in court. In Husted v. A. Philip Randolph Institute, decided in 2018, the Supreme Court looked at an Ohio process that treated a voter's failure to vote for two years as a trigger. Ohio sent those voters a notice, and if they did not respond and did not vote in the next four years, the state removed them.

The challengers argued that this violated the NVRA's ban on removal "by reason of" failure to vote. The Court, in a five-to-four decision written by Justice Alito, disagreed. It reasoned that Ohio did not remove anyone merely for failing to vote. Ohio removed people only if they failed to vote and failed to respond to a notice and failed to vote for a further period. The failure to vote was a trigger for sending the notice, not the reason for removal, and the actual ground was the apparent change of residence, which the statute permits. The decision rested on the text of the law and on a reading of what the 1993 Congress wrote.

Whatever your view of the policy, the case settles a useful point. Section 8 is not a suggestion. It is a statute with operative words, and a state that follows its procedures, including a notice, has room to design a process that works.

HAVA, the statewide database

Nine years after the Motor Voter law, Congress took another step. The Help America Vote Act of 2002, passed after the 2000 election's troubles with ballots and counting, required each state to build a single, computerized, statewide voter registration list. Before HAVA, many states kept their rolls county by county, and a voter who moved across a county line could end up on two lists. Anyone who has ever seen a mismatched mailing list will see the problem.

HAVA also requires states to perform regular list maintenance on the statewide list, and it requires that the list be coordinated with other state records, including the state's records of deaths and of felony status. The law pushes states to use the data they already have, which is the cheapest and fairest way to catch obvious errors.

For the details of how HAVA fit into the long story of American voting, the timeline in From the Secret Ballot to HAVA, a Timeline of How Americans Came to Vote is a good companion to this post.

Data sharing between states

A statewide list solves the county problem but not the state one. A voter who moves from Ohio to Florida may remain on Ohio's list for years, and Florida may have no way to know. Over the past decade, states have built tools to share data. The best known is a nonprofit consortium called the Electronic Registration Information Center, which states join voluntarily and through which they compare registration records and motor vehicle data to identify voters who have moved. Some states have joined and some have left, and the debate over its design and its costs is a live one.

Earlier systems that compared names and birth dates across states had a serious weakness, which is the one every honest conservative should acknowledge: matching on name and date of birth alone can wrongly flag two different people who happen to share both. That is exactly why the notice-and-wait rule exists. A record match is a reason to send a notice, not a reason to remove a name. A state that treats a raw match as proof invites a lawsuit and, worse, the unjust removal of a lawful voter.

The argument, numbered

Here is the case for taking list maintenance seriously, in six steps.

1. The law requires it. Section 8 of the NVRA and the statewide list requirement in HAVA are federal statutes. A state that ignores them is not being cautious; it is violating the law.
2. Accurate rolls protect every voter. An inflated list does real harm even when nothing improper happens, because it makes turnout look low, it clogs the poll books, it wastes money on mailings and it creates the opportunity for error. A clean list makes for shorter lines and faster counts.
3. Dead voters cannot object. A name that stays on the rolls after death is a name that someone could try to use. That is a prevention argument, not an accusation. We lock the door because the door exists.
4. Moved voters should vote where they live. A person who has moved should be registered at the new address, and the old registration should not hang around as a second chance at a ballot. Most mistakes here are innocent, and a clean process fixes them without blame.
5. Process protects the innocent. The notice-and-wait rule, the 90-day quiet period and the bar on removing people for not voting exist to make sure that cleaning the list does not hurt a real voter. A good state follows them to the letter.
6. Transparency builds trust. A county that publishes how many names it has removed, why, and how many it has restored gives voters a reason to believe the process is honest.

Nothing in that list claims that rolls are full of fraud. It does not need to. It is an argument about doing a clerical job carefully, which is a rather unglamorous way to defend self-government, and which is exactly the point.

The strongest objection, answered

The best objection to aggressive list maintenance comes from people who worry that it will be used to purge legitimate voters, disproportionately people who move often, such as young adults, renters and members of the military. They point to cases where lists were cleaned with faulty data and eligible voters found themselves turned away at the polls.

That is a legitimate concern, and I will not wave it off. Here is the answer. First, the concern is an argument for doing the job properly, not for skipping it. The law's own safeguards, notice and waiting and the quiet period, are built to prevent the problem. Second, a voter who has been wrongly marked inactive can usually still vote by confirming his address, and many states allow same-day correction, with a provisional ballot as a last resort under HAVA. Third, the remedy for errors is better data and better procedures, and conservatives, who believe in competent administration, should be the loudest advocates of both.

The other half of that argument is the one I would press on my own side. If you want clean rolls, be willing to pay for them: fund the election offices, give them modern tools and insist that they follow the statute's procedures to the letter. A sloppy purge discredits the cause of clean rolls faster than any opponent could. A careful one wins.

Why the Founders would recognize the idea

The Constitution gives the states the first move in running elections. Article I, Section 4, Clause 1 provides that "The Times, Places and Manner of holding Elections for Senators and Representatives, shall be prescribed in each State by the Legislature thereof; but the Congress may at any time by Law make or alter such Regulations." List maintenance is a classic piece of "manner." The states keep the lists, and Congress, using that second clause, has set a floor of federal standards.

That division is worth admiring. It lets the states design their own systems, which is the conservative idea of federalism, while ensuring that no state can let its rolls rot and leave the national count worse off.

What to look at in your own county

You do not have to take any of this on faith. Your county or state election office publishes information about its list maintenance, and federal law requires that records of list maintenance be available for public inspection. You can ask, in writing, a few concrete questions.

• How often does the county run its list maintenance program, and when did it last finish?
• How many notices were sent in the last cycle, and how many came back?
• How many names were moved to inactive status and how many were removed?
• Which data sources does the county use, and does the state belong to a data-sharing program?

A clerk who answers those questions plainly is running a good office. A clerk who cannot is a reason to call your county commissioner. And you can check your own registration in about a minute on your state's website. It is the one civic errand that takes less time than renewing a library card.

The case in brief

1. The National Voter Registration Act of 1993 is known for registration at the motor vehicle office, but Section 8 also requires states to make a reasonable effort to remove voters who have died or moved.
2. The law sets the process: no removal for failing to vote alone, a notice and a wait through two federal general elections for movers, and a 90-day quiet period before federal elections for systematic programs.
3. Husted v. A. Philip Randolph Institute (2018) upheld Ohio's process, and the Help America Vote Act of 2002 required a statewide computerized list that states now improve with data-sharing tools.
4. Accurate rolls serve every voter by shortening lines, saving money and protecting the integrity of the count, as long as the safeguards that protect eligible voters are followed.
5. List maintenance is a clerical duty, and a state that does it carefully and publishes the results earns trust.

What you can do: check your own voter registration on your state's election website today, and ask your county election office in writing how it runs its list maintenance.
