Okay, but now we have to be sure of what we are talking about.
Both sides tend to say "vote(r) fraud" when this subject comes up, BUT that is not the issue, strictly speaking. If it's really "voter fraud," the issue is about deliberately casting more than one ballot, voting in the name of someone else, or something like that. This does occur.
But when referring to the problem, to keep talking about fraud is a way of excusing the deliberate invitation to have voting errors and inaccuracies that seems to have been a nationwide epidemic last autumn.
So if ballots are just blowing in the wind, so to speak, and available to unknown parties thinking of engaging in vote fraud, the people who benefit from such fraud will take the opportunity to exploit it.
But in discussions about the voting results and procedures, the tens of thousands of invalid votes that were cast last year in each of the half dozen states that have been most under discussion are not included in the telling by defenders of the voting rules that were put in place expressly for the 2020 election. The election officials who created this porous system and knew what would happen say they were just helping to make it easier for people who couldn't get to the polls in the usual way and pat themselves on the back for having done this to our elections. And then we also get their sympathizers covering for them by speaking of vote "fraud" or saying that the number of people arrested and convicted of having changed someone else's ballot, for example, is minimal. "Hey. It's not significant," they so. But it matters what they are pointing to--a handful of convictions of identified criminals or tens of thousands or more cases of invalid ballots being counted as genuine but no individual person has been identified, arrested, and prosecuted.
