In 2008 FOX had an expert on voting machines on. He demonstrated how a vote could be for one person in the machine and print out something else.
In otherwards, with the electronic machine, your printout may not mean your vote registered to the person you voted for.
Right, so one of the only reasons to have an electronic voting machine is to print properly-formed ballots.
You can also have a pseudosecret ballot election, where each voter is given a random key, and a receipt with a list of candidates he voted for, and then the key-vote pairs are published and the voter can verify later that his vote was correctly counted.
If you can view the printout and verify it, how can it not be for the person you wanted?
