In France, vote by mail was used between 1946 and 1975. It was stopped due to too much fraud (even if less than 2% of the population used it).
Just the fact requiring a valid ID is a contentious idea in the US is baffling when seen from here. I think more people in the US should check how elections are done in other countries (and not just 3rd world ones).
>>It is unlikely that there has been a significant increase in electoral malpractice since the introduction of postal voting on demand in 2000; available figures suggest that 32 convictions were made from 1994–99. In both periods, the offences arose almost exclusively from local elections, and related to a tiny proportion of all elections contested.
Again, the facts are clear, but that doesn't stop the baseless fearmongering. A direct quote from your source:
>>There is no evidence to date suggesting that electoral malpractice has occurred as a result of pilots of various forms of electronic voting. However, serious questions about the security of electronic voting from organised fraud remain unanswered.
It flatly concedes that no evidence of voter fraud from electronic voting exists, but then somehow concludes that serious questions remain unanswered. Simply absurd.
None of this changes the fact that mail-in voting in the United States is objectively and measurably secure, and that instances of fraud are so miniscule that claims of it having an impact on election outcomes are provably false.
