“Wouldn’t it be easier to replace the entire ballot?”
Yes it would, but using the machine to change the ballot doesn’t require a person to do anything.
It would also be consistent with these claims that votes were electronically switched for Biden. But the hand count of paper ballots matched.
No offense, but I think that “ballot scanners with frickin’ vote erasing lasers on their heads” is going a bit too far into tinfoil hat land.
Not only would the scanners need ink erasing lasers installed, they would also need a means to print a new vote on the ballot, and do it in such a way that it matches the ink color and penmanship of every other mark on the ballot.
Oh, and both the erasing laser and the color print head has to be undetectable by maintenance personnel.
