“In the United States, previous elections were falsified through postal voting … they bought ballots for $10, filled them out, and threw them into mailboxes without any supervision from observers, and that’s it,”
Problem - That’s not the way vote by mail works.
You register to vote and place a signature on file.
You get your ballot in the mail and vote.
You put the ballot in the mailing envelope and sign the back of the envelope.
When the ballot is returned, they compare the signature on the envelope with the signature on file, if it matches, the ballot is set aside for counting.
If there’s a PROBLEM:
A) Missing signature
B) Signature doesn’t match
C) Ballot damaged or unreadable
D) Ballot already recorded as present
The ballot gets returned to the voter for correction, assuming there’s enough time for it to be corrected.
What Putin describes wouldn’t work, because the fake ballots either wouldn’t have a signature, wouldn’t have a valid signature, or wouldn’t correspond to a registered voter.
