The single largest case of voter fraud in this countries history happened in North Carolina in 2018. That was committed by a Republican.
If you investigate the voter fraud instances in Trumps own listing you will find that the majority of them are committed by Republicans.
Combine this information with the efforts by Republicans to suppress the vote and you can see the problem. In North Dakota, the Republican-controlled legislature passed a law that required all citizens to have a physical mailing address to be able to vote. Sounds resonible right? Well, this was after a Democrat won a Senate election in that state thanks in large part to the Native American population. Most Native Americans live on reservations in that state and part of living on the reservations is a lack of physical mailing addresses.
Nothing about having a physical address is going to make voter fraud less likely. It's plain as day that Republicans are just interested in suppressing the votes of people who vote against them.
