Almost two million ballots were disqualified in the 2000 election because they registered multiple votes or none when run through vote-counting machines.

As a result of the confusion in 2000, the U.S. Congress passed the Help America Vote Act to help buy improved voting equipment and to train poll workers and election officials across the country.

While only 10 percent of voters cast their ballots electronically in 2000, almost a third of U.S. voters in tomorrow's election are expected to use electronic voting machines.

But studies have shown that electronic voting machines are less reliable than paper ballots in accurately counting votes. The Caltech-MIT Voting Technology Project, a study group set up to analyze elections dating back to 1988, found that old-fashioned lever machines were actually more accurate than electronic voting machines.
