Why not have a machine that asks if you are sure this how you wanted to vote, and prints a receipt? People could then pull a numbers report and make sure it went to where it was supposed to.
I don't get that either. It seem so simple. When I pay a bill online, I always print out a confirmation page. As usual, capitalism is way ahead of government.
The one problem is that printed ballots, and probably receipts would need to stay inside the polling place. Otherwise, the voter could be 'detained' by some 'friends' just to make sure he voted the way he was instructed to. Then they could beat the tar out of him if the receipt said otherwise.
That said, all Dems should be required to use a butterfly ballot!
