text: why don't voting machines...? ...encrypt your vote using md5 in combination with a password of your choosing, allowing the result to be stored yet be unreadable to anyone except the voter themselves?  then you could securely check your vote in the privacy of your home from a nationwide database without anyone else being able to decipher it.  voter id #: state: we have your vote recorded as:  11mc8u19dhj239dj9wh32934aij  then, grandma simply needs to run her password and candidate selection on her home computer through a simple widely available md5 encrypter and be confident her vote was counted!!! because that way, votes couldn't be changed in anyone's favor.
