Electronic Voting Machines Are Not Secure
The "network connectivity" hacking issue is a fools issue.
Professionally speaking, the best way to hack any digital voting computer is to own the platform. That way I could build my own software, control the firmware and use my own algorithms to control who wins the election in real time. Why would I risk having a wired or wireless network connection that can be questioned or hacked by others. Rather, I would employ a much more robust security system called CPI. Company Proprietary Information. An act of Congress can’t even breach that firewall. And, I would have dominion over the voting populace.
So, may the highest bidder win! Let that sink in. ;-)
