It seems like most people here believe there is no evidence of mail-in voter fraud (for some reason...). Here’s a huge list of convictions for ‘fraudulent use of absentee ballots’: https://www.whitehouse.gov/sites/whitehouse.gov/files/docs/p... Edit: some might think this list is comprehensive, but the first page says it is a ‘sampling’, a 400-page sampling.
To justify severely hampering the public’s right to vote you would need to demonstrate a pattern of recent fraud efforts that swung elections to the side committing the fraud. as far as I know there are exactly zero of those at the federal level, and probably near zero at any level of government.
There is no legitimate independent body studying this who believes voter fraud in the United States justifies the widespread disenfranchisement strategy the GOP is applying in so many elections across the country. Full stop.
