The disputed election results in Florida introduced a new term into popular speech.Americans began talking about "chads." Whether it was "hanging chads," "pregnant chads" or "dimpled chads," it amounted to the same problem.It meant that a voting machine had not cleanly punched out a bit of paper,called a chad,when the voter made a choice.As a result,the ballot would confuse a vote-counting machine and make the choice unreadable.
