That is funny considering the primary benefit of electronic voting machines is speeding up the gathering of results. I'm not sure how you expect us to manually count 150 million ballots quicker without using any hackable electronics.
Otherwise, you are still falling into the same trap.

We are back to needing a widespread conspiracy that operates in several states and can attack in a variety of different ways.
