The Nov. 1996 issue of Popular Science, pp. 71-74, has some interesting info about direct-recording electronic (DRE) voting (used by around 4.3 percent of the voters) and polling. Around 60 percent of all votes are now indirectly counted electronically (punch cards, scanners). A company called Sequoia Pacific Voting Machine Co. makes one type of DRE equipment. Anybody in California available to get the equipment's capabilities ?
