Chances are you’ve heard something about a mistake that allowed 1,259 people in Oregon to register to vote without demonstrating that they were U.S. citizens.

Despite clear indications that state officials have worked during the last couple of weeks to fix the issues that allowed these registrations to occur, you’re likely to hear more about this as Election Day draws closer.

That’s because some people are taking advantage of the mistake to sow doubts about Oregon’s election process, from voter registration to the state’s vote-by-mail system.

To be sure, it’s worthwhile to ask questions and to make certain we identify and fix the occasional glitch in the system. People who aren’t registered should not be able to vote.

But what happened in this case is not any sort of symptom that something is seriously haywire — and it certainly isn’t any justification for efforts to undermine what has been Oregon’s decades-long effort to systematically remove roadblocks to voting.

Here’s the background:

As officials answered questions raised by a left-leaning think tank that was gathering information on automatic voter registration, they learned that staff members at the state Driver and Motor Vehicle Services had automatically registered 1,259 people to vote even though those people had not provided documents that proved citizenship. (As of September, for the sake of perspective, Oregon has about 3.025 million registered voters.)

Since 2016, the state automatically has registered people to vote when they obtain or renew driver’s licenses and state-issued identification cards if they have documents that prove citizenship. But, over the years, DMV staff members mistakenly noted in those 1,259 instances that the person registered through the “Motor Voter” program had provided the required documentation when they had not actually done so.

Ten of those individuals actually voted — although it turns out that one of the 10 is a citizen who has voted for years and just didn’t bring documentation to prove citizenship when renewing a license.

Of the remaining nine, none of them voted in an election decided by a single-digit margin, so their ballots didn’t affect the outcome of any race or ballot measure.

Those people who have been mistakenly registered to vote have been dropped from the rolls. And work is underway to close the flaws in the system that allowed this to happen.

Despite all that, some politicians are using the incident to renew their calls to eliminate automatic voter registration. Others are using what amounts to a minor gaffe to throw shade on all of Oregon’s voting system, including the state’s vote-by-mail process, which has helped make the state a national leader for turnout. (The vote-by-mail system has the added benefit of leaving a paper trail, which undoubtedly helped state officials as they tried to get a handle on the mistaken registrations.)

Oregonians across the state, of every political stripe, have worked hard for more than a half-century to remove roadblocks to voting — and to build a vote-by-mail system that sets the standard for the United States.

It would be a shame if we rolled back any of Oregon’s proud history of expanding the franchise because of a minor mistake.
