I like the machines we use; I don't understand why everyone doesn't use them. We fill in ovals with a black marker, then insert the paper into a reader. The reader determines whether I've invalidated my ballot by voting for too many people or crossing parties in a primary. If so, I get a chance to start over. The machine counts votes electronically, but saves al the ballots in case the machine is compromised.

What is the reason these machines aren't used everywhere? I don't get it.
