CINCINNATI — All five voting systems used in Ohio, a state whose electoral votes narrowly swung two elections toward President Bush, have critical flaws that could undermine the integrity of the 2008 general election, a report commissioned by the state’s top elections official has found.
At polling stations, teams working on the study were able to pick locks to access memory cards and use hand-held devices to plug false vote counts into machines. At boards of election, they were able to introduce malignant software into servers.
Ms. Brunner proposed replacing all of the state’s voting machines, including the touch-screen ones used in more than 50 of Ohio’s 88 counties. She wants all counties to use optical scan machines that read and electronically record paper ballots that are filled in manually by voters.
Florida, another swing state with a history of voting problems, is also scrapping touch-screen machines and switching to optical scan ones for the election. Such systems have gained favor because experts say they are more reliable than others and, unlike most touch screens, they provide a paper trail for recounts.
Ms. Brunner, a Democrat, succeeded J. Kenneth Blackwell, a Republican who came under fire for simultaneously overseeing the 2004 election and serving as co-chairman of President Bush’s re-election campaign in Ohio.
