"Voting fraud is extremely rare in the US, and voting by mail is no exception. In the past 20 years, over 250,000,000 votes have been cast by mail, and according to data from the Heritage Foundation, there have been only 1,285 proven cases of voter fraud."
"Studies done by such organizations as Stanford University have found that voting by mail does not favor voter share or turnout of either major political party. Expanding access to voting by mail is generally considered great for all voters and their ability to exercise their right to vote."
So, then what would be the objection to an absentee voting, being identified? That seems to be the fly in the ointment.
