So, vote thieves use your SSN to vote 'before' you; you then show up to vote, and your ballot is thrown into the "questionable" hopper. Then your vote languishes because the invalid vote is already in the system. Who your SSN originally voted for is in limbo and can't be eliminated because of voter anonymity.

How will the thieves do that exactly if multi-factor authentication is used? Go ahead, enter a false SSN. What’s the validation that it is actually the right person voting? You can steal my SSN, but you cannot steal my pin.
