no??? 11 other countries have full mail in voting (Canada, Denmark, Germany, Iceland, Liechtenstein, Luxembourg, New Zealand, Poland, South Korea, Switzerland and the United Kingdom). 22 others have conditional mail in voting, for various reasons. mail in voting does not raise and problems with legitimacy, it just makes it easier for people to exercise their right to vote, which conservatives hate because they are a significant minority of the total electorate. if we had 100% turnout republicans
would lose basically all elections except for a handful of states, which is why they spend so much time illegally trying to prevent people from voting; as well as by creating new barriers to voting. there has been no substantial voter fraud in many many decades in this country. and funny enough, most of the instances in the last 10 years have been Trump supporters trying to cast extra votes for Trump.
