Oh for crying out loud.
Far easier for a single, high-school dropout campaign worker to simply throw a box of paper ballots in a dumpster.
If you have (1) unlimited access to the machine, (2) and can take the case apart and (3) can solder a daughtecard onto the circuit board -which is obvious for later fraud investigation- and can (4) control thousands of machines in real time to “blank the screen and change the vote” from only yards away from dozens? thousands? of polling stations....
Really? This is a concern?
Exactly. If someone found out that you could access them remotely AS THEY SAT at the polling places and without physically touching them, THEN I would be worried.
