Computerized voting was supposed to be the cure for ballot fiascos such as the 2000 presidential election, but activist groups say it has only worsened the problem. Lawsuits have been filed in at least nine states, alleging that the machines are wide open to computer hackers and prone to temperamental fits of technology that have assigned votes to the wrong candidate. About 80 percent of American voters will use some form of electronic voting in the November election. New York University's Brennan Center for Justice released a one-year study last month that determined that the three most popular types of U.S. voting machines pose a real danger" to election integrity. More than 120 security threats were identified, including wireless machines that could be hacked "by virtually any member of the public with some (computer) knowledge" and a PC card. Diebold spokesman David Bear said his company's technology "has proven to be more accurate" than punch cards. The company's former CEO, Wally O'Dell, authored a 2003 Republican fundraising letter that promised, "I am committed to helping Ohio deliver its electoral votes to the president next year." Bear said there has been no evidence in any election of hackers breaching electronic security measures. However...Lowell Finley, co-director of Voter Action...said, "We had dozens of affidavits from voters in New Mexico who said they touched one candidate's name, but the machine picked the opponent," he said. In the state's biggest county, home to Albuquerque, touch-screens machines purchased from Sequoia lost 13,000 votes.
