Exactly, it is in fact very informative to look through their examples, because it shows a very robust system that's catching very very rare cases, and if there were more widespread fraud it would be very evident through the same mechanisms used to catch these very very rare cases:

Every case I checked was something like this, here are two that I randomly clicked on from my state right now:

> Alex Campbell, Republican city councilman and mayor pro tem of Crescent City, California, falsely claimed his residence was within city limits when submitting his candidacy for councilman. Campbell was charged with two felony counts of perjury and one count of false declaration of his candidacy and pleaded guilty to one count of making a false declaration of candidacy. He faces up to two years of probation and $20,000 in fines for his charge. https://electionfraud.heritage.org/case/200148

> Nickey Huntley was involved in a scheme that offered cigarettes and money to homeless people on Skid Row in exchange for fake signatures on ballot initiatives and voter registration forms. This resulted in hundreds of fraudulent signatures. He pleaded no contest to one felony count of circulating an initiative or petition containing false, forged or fictitious names. Huntley was sentenced to 3 years’ probation. https://electionfraud.heritage.org/case/201251
