Agree somewhat, but there are bright minds at work with cyber security and many of them used to come from TU. You can secure anything you want if you really want to. The security issue would be the inside jobs. I am talking more a point of convenience.
Right now, personally, I think we need to go back to pen marked ballots that are counted by hand by the independent accounting house of Price Waterhouse Coopers. I don't trust the optical scanners used in OK because they're easily hacked by whoever is calibrating them. Other ideas, non-partisan ballots, randomly generated ballot order.
