Voter fraud is 0.0001%. There is no need for any voting laws to be changed. The repubs did not like the results so they changed the voting methods that the dems like. Such as mail in, drop boxes, absentee, Sunday voting etc. The table was set for this in 2013 when the conservative supreme court gutted the 1964 Voting Rights Bill. They removed the part where election officials had to get special permission from the DOJ to make any voting rule changes.
If you want to talk about cheating in 2020, Chump tried to get Kemp in GA to "find" 11,000 votes. To his credit, he taped the phone call and refused to do so. If that ain't cheating then I don't know what is.
