Oh, this is where the fun starts.
This is the thing about statistics, it's all about how you break them down.
If you take the number of convictions for voter fraud across the entire USA since, according to one site I have found
https://www.heritage.org/voterfraud , 1,132
proven cases of voter fraud since 1979 is indeed a teardrop in the ocean, it's insignificant. But I bet once you start breaking things down by state and year, California features much more often than Alaska as an example but I haven't even started breaking things down yet, I'll bet certain patterns will start to form.
And, of course, I must emphasise that this is only PROVEN cases, not allegations and certainly not the cases where they get away with it year upon year (isn't voter registration day the day the dead rise in Chicago? That's how the old joke goes anyway).
Don't get me wrong, I'm not suggesting it's widespread BUT it can be critical if used in the right way, and if there's any hint of dishonesty in any election then there should be steps taken to ensure that said dishonesty cannot happen, that the system cannot be abused by any side (I'll bet they're both as bad as each other, when you break things down) in such a fashion, that the election is as free, honest, open and transparent as is possible, otherwise the system gets seen to be faked and flawed so "voter apathy" becomes the way forward and that's never a good thing.
