I just came across this story in my travels. The story is about indictments in KY of election officials for changing electronic votes at the voting machine.
Basically, the voters would cast their votes and press the “VOTE” button at the bottom of the ballot. Then they would walk out. The vote button actually was programmed to bring up a confirmation of the ballot. Many voters would just walk out of the voting booth. The poll workers that were in on the fraud would then step into the booth and change the votes to whatever they wanted.
We need to have auditable voting machines.
