Possible That Dominion is a distraction and examining sorce code will show no fault after investigation.

Intel ME engine was / is used by 3 letter agency's to simply bypass all security on a computer and read and write as it sees fit. If those machines were connected to the internet then its possible this could be done in real time.

The Dominion Vote swapping code could be injected at the ME level, leaving no trace of foul play in the source code. The code would look legit and if they find a problem it could be put down to a glitch!

I suspect this to be the case only because of the Jill Stein red meat almost begging us to look at the base code of Dominion.
