Editors at the Washington Examiner lament the number of noncitizens casting ballots in American elections.

Illegal immigrants and other noncitizens should not be voting in U.S. elections. Alas, too many do.

When Rep. Bob Livingston of Louisiana led Republican opposition to what was nicknamed the “Motor Voter” bill in 1993, he dubbed it “Auto Fraudo.” Thirty years to the week after President Bill Clinton signed the bill into law, it seems an apt monicker, according to a May 23 report from the Public Interest Legal Foundation.

As PILF rightly argued, the Motor Voter law needs to be modified and updated. Its guarantees for greater transparency should be kept or even strengthened, and its loopholes allowing fraud should be closed.

The new report, the most recent in a series of PILF studies from across the country, showed that in the past 20 years in Chicago, 394 noncitizens were registered to vote despite properly telling election officials they were not citizens. Of those, 20 cast a total of 85 ballots in real elections. The average length of time that noncitizens stayed on the voter rolls before errors were caught was 7 1/2 years. One noncitizen was on the rolls for 30 years!

It’s bad enough for these incidences to occur, but the numbers must substantially understate the problem. The report covers only those noncitizens who self-reported their status but were registered against Illinois law and arguably against the U.S. Constitution. Incentives weigh overwhelmingly against self-reporting, so it stands to reason that many multiples of the reported numbers are on Chicago’s voter rolls.

This is not a problem unique to Chicago. PILF reported that Maricopa County, Arizona, has had 222 foreign nationals on voter rolls; Fairfax County, Virginia, 1,334; San Diego County 264; and there were 1,290 more in 10 other counties where records were examined. In Virginia overall, 5,556 noncitizens were removed from voter rolls, but only after 7,474 votes were cast illegally.
