Open source for voting machines has got to be one of the dumbest ideas I've ever heard. If you want to GUARANTEE that software hackers (hired by Democrooks or whoever) will fully understand how to attack or compromise a voting machine, make sure they have full access to the source code to expose exactly how they work. Idiotic.
Then explain the relative lack of exploits for Apache or SE-Linux.
The "Count Every Vote" mantra is what the Dims in Washington State were chanting, just before they packed in 2000 more ballots than there were voters, and before they had over a thousand felons vote. They are very good are materializing phantom votes, and they want every one counted.
