Shortly before the 2012 Indiana decertified a certain voting system. I actually watched from afar it being tested in the primary. When we came back for training the clerk explained the decertification and stated we had new voting machines She told us the states still using the machine Sure enough on election night those areas came in late for Obama
Earlier this year I watch a video showing how the Diebold machine switched the vote. It appeared to be the exact system we had used and I had watched our local team test.
If they have not been removed from OH, VA, TX , WI, CO and others this is the first act that MUST be done
Somewhere there is a 223+ report explaining the problem. Our county was listed on page 223
They have been removed from my county and a from a few other places in VA that I know about. But I’m not sure about the state as a whole. As a SW engineer I could think of a dozen ways to tilt the vote using intentional SW bugs that would be unfindable through inspection and difficult to test for.
