Diebold's voting machines are even less secure than previously suspected. Inspection of a Diebold machine by the open Voting Foundation revealed that all it takes to get a Diebold machine to boot a modified, crooked operating system is the flip of a switch, a task that can be accomplished in a brief moment using nothing but a screwdriver. Diebold has strenuously resisted calls for its voting machines to be fitted with paper audit-tapes that would record the votes cast for comparison against the electronic tally, and has used legal threats to keep critics from publishing memos detailing earlier flaws discovered in its machines. If you want to steal an election, use a Diebold machine.
Upon examining the inner workings of one of the most popular paperless touch screen voting machines used in public elections in the United States, it has been determined that with the flip of a single switch inside, the machine can behave in a completely different manner compared to the tested and certified version.
"Diebold has made the testing and certification process practically irrelevant," according to Dechert. "If you have access to these machines and you want to rig an election, anything is possible with the Diebold TS -- and it could be done without leaving a trace. All you need is a screwdriver." This model does not produce a voter verified paper trail so there is no way to check if the voter's choices are accurately reflected in the tabulation.
