Is it, though?
My belief is that voter fraud is basically a non-issue, that it doesn't really happen very much at all, and that it is a bogus argument put forth by the Republicans to give an excuse for why they are so consistently fighting to not allow people to vote.
Google search "does voter fraud really happen", and "how bad is voter fraud":

I can't find any results that don't back up my belief. Can you?
The Heritage Foundation, a far-right think tank, has a page on voter fraud: https://www.heritage.org/voterfraud
But, in my opinion, it's kind of amazing that they leave the page up. The purpose of this page is to document and expose how bad voter fraud is, and they provide a searchable database on all the cases they have found and confirmed. Their database goes back to 1982, and they have found... 1340 cases of voter fraud.
This is an embarrassingly low number, isn't it? A few thousand fraudulent votes over the last 40 years?
Also, it's not like these cases are cases of people manufacturing thousands of votes. You can check for yourself, the entire list is here:

These are overwhelmingly on the order of "a single extra vote was cast" because someone voted in two districts, or mailed in an absentee ballot for a deceased relative.
Meanwhile, do Republicans work to suppress votes? I think it's hard to argue otherwise in good faith:

Why does Mitch McConnell say that the idea of making election day a national holiday is a "naked power grab" for Democrats? Shouldn't making it easier for people to vote be a "good idea that strengthens our democracy"?

Another belief of mine is that it's common knowledge in politics that the more people who vote, the worse Republicans fare in elections.
The Republican professional politicians are usually better at not openly admitting such things, but Trump gave us another example of "saying the quiet part out loud" with his usual eloquence: "They had levels of voting, that if you ever agreed to it you'd never have a Republican elected in this country again"

Why would Trump say that?
The Republicans are trying to reduce democracy. They lost the support of the people. They have only won the popular vote once in the past 30 years. Rather than changing their platform to try to appeal to more voters, they've decided that the people are their enemy.
