You have no idea how much money has been spent on updating voting machines. However, you cannot take the evil out of men's hearts.
Scientific American has an amusing article called "fixing the vote" about all the wonders of electronic voting machines and the need to keep them secure and easy to use, etc. They manage to mention registration in passing twice, I think. So you get Diebold machines with back-doors programmed in, tsk tsk; meanwhile 16,000 fraudulent registrations are detected in L.A. County in 1996 and nobody does anything and no more reports are forthcoming...
