Another precinct in Charlotte, NC is reporting "calibration" problems. A woman reports that she tried to pick Romney three times, and it registered Obama all three times. Fortunately she was astute enough to confirm before submitting the ballot, but this is still intolerable. We should not have the manner in which we select political representatives come down to unreliable electronic machines (and I don't think it's the machine's inherent reliability that is in question, I think it is deliberate manipulation).
My local polling place used to have a large board where you press a button corresponding to your choice and it illuminated a big arrow pointing to your choice. Once done you hit a submit button. As far as electronic voting goes, that worked pretty well and was unambiguous. But they have since changed over to a Scantron form where you fill in bubbles like you did on exams back in school. I like this system better. They can scan the form for all the benefits of computerized tabulation, but there is still an unambiguous paper ballot backing each vote. Entirely electronic systems should be outlawed by Constitutional amendment, IMO. They are a threat to our whole electoral process.
