Shari from An Old Soul pointed me to this post at MouseMusings that points us all to BlackBoxVoting.org's description of the core problem with eVoting - not the touchscreen issue though - it's the central tabulator that Bev has good reason to worry about:
Issue: Manipulation technique found in the Diebold central tabulator -- 1,000 of these systems are in place, and they count up to two million votes at a time.
By entering a 2-digit code in a hidden location, a second set of votes is created. This set of votes can be changed, so that it no longer matches the correct votes. The voting system will then read the totals from the bogus vote set. It takes only seconds to change the votes, and to date not a single location in the U.S. has implemented security measures to fully mitigate the risks.
This program is not "stupidity" or sloppiness. It was designed and tested over a series of a dozen version adjustments.
As usual, I'll encourage you to read the whole story. It's incredibly frightening and depressing. But they've only got this system in 30 states so far. It looks like some votes may be counted this year. Maybe one of them will be yours.
