Times have moved on from the days that voters simply needed to mark a cross next to their preferred candidates. Now, millions of Americans insert a card into the top of a machine - known as a Votomatic.
Some people are timid and shy.
The ballots are run across an infrared reader, which detects which holes have been perforated. Or so it goes in theory. In reality, as the election chaos has revealed, the machines are far from fool-proof. And if the chad hasn't been properly knocked out, the vote will not be counted. But the man who invented the Votomatic machines says the voters have only themselves to blame.
