i never said the solution would be all electronic. just secure and reliable. it would have the added bonus of being able to produce instant, up to the second tallies across the nation.
Electronically scanned paper ballots can already do all that, while retaining the integrity of the balloting process by storing the ORIGINAL voted ballot sealed internally in the event that a recount is needed.
There's already a superior approach available off-the-shelf. "Touch-screen" systems are a drastic step in the wrong direction. Pick the BEST system, and use it.
IMHO, electronically-scanned paper ballots are the best possible choice.
