Americans have relied on computers to tally votes since at least 1964, when two Georgia counties used them to count punch-card ballots in a primary election. Over time, high-tech election systems largely supplanted paper ballots and gear-and-lever machinary, a trend hastened by the contested 2000 presidential election between George W. Bush and Al Gore. (Remember hanging chads?) But ever-greater reliance on digital voter registration, electronic voting and computerized tabulation have created the opportunity, at least, for hackers to sabotage elections, and Americans aren’t the only ones who are fearful.
