I wish it could be safe, but real electronic voting fraud may be far more common in practice:

https://www.youtube.com/watch?v=zsNXnAv131g Computer Programmer testifies that Tom Feeney (Speaker of the Houe of Florida at the time, currently US Representative representing MY district ) tried to pay him to rig election vote counts.

Usually they can be detected when exit polls differ from the voting results. But that seems common nowadays. So that is why I think that voting fraud may be common.

But back to the whistleblower.. How many have accepted the money? And how many of them are able do some underhand programming? Sometimes just to leave small security holes.

I don't think that MIT can detect them that easily. For a long time we did not even know the NSA encryption was compromised by NSA themselves.
