Wisconsin Goes Open Source
Wisconsin's electronic voting bill, passing overwhelmingly despite Republican rule, states:
And
"If a municipality uses an electronic voting systm for voting at any election, the municpal clerk shall provide any person, upon request, at the expense of the municipality, the coding for the software that the municipality uses to operate the system and tally the votes cast."
And
"If the device consists of an electronic voting machine, it generates a complete paper ballot showing all votes cast by each elector that is visually verifiable by the elector before the elector leaves the machine and that enables a manual count or recount of each vote cast by the elector."
