Slots versus Voting Machines

The conventional media is slowly waking up to the problem of the vulnerability of the machines upon which we are forced to vote. See this graphic from the Washington Post which compares slot machines and voting machines, in which slot machines can be audited. Example: Las Vegas slots are certified by a public agency kept at arm's length from the manufacturers. Voting machine certifications are done by for profit companies chosen and paid by the manufacturers, with no public information on how the testing is done.
