An audit of last November's general election in the Cleveland area has found that hundreds of votes were lost, that others were recorded twice and that software used to count the ballots was vulnerable to data problems. In a state that was pivotal to President Bush's election and re-election, Cuyahoga County, which includes Cleveland, has seen more than its share of recent election troubles. Lines at polls there were hours long in the 2004 general election. And in the primaries last May, the county's first experience with electronic voting, poll workers were absent or poorly trained, computer cards on which votes had been recorded were lost, and one polling place opened hours late. The audit found that some batches of ballots registered in optical scan machines had been scanned twice, producing a double count of those ballots. Other ballots were deleted because of flawed data and, owing to human error, were not rescanned, the committee found. The optical scan and touch-screen machines used in the county were made by Diebold Election Systems Inc. The audit committee said Microsoft's JET file-sharing database system, which Diebold used, was known to have previously had problems that could result in corruption of the database. The audit committee was allowed only a limited review of the data collected by Diebold. The panel tried to gain access to the raw data, but Diebold claimed that the information was proprietary. Barbara Simons, a ... past president of the Association for Computing Machinery, said: There is no excuse for Diebold's having used such an insecure and unreliable database. There were far more reliable databases available over 20 years ago." The committee called for extensive changes to ensure the integrity of future elections, among them streamlining the process by eliminating either optical scanner or touch-screen machines.
