Tests on an electronic voting machine that recorded shockingly high numbers of extra votes in the 2010 election show that overheating may have caused upwards of 30 percent of the votes in a South Bronx voting precinct to go uncounted. WNYC first reported on the issue in December 2011, when it was found that tens of thousands of votes in the 2010 elections went uncounted because electronic voting machines counted more than one vote in a race.
A review by the state Board of Election and the electronic voting machines’ manufacturer ES&S found that these “over votes,” as they’re called, were due to a machine error. In the report issued by ES&S, when the machine used in the South Bronx overheated, ballots run during a test began coming back with errors. “After lunch [when the machine was idle for about an hour] almost every ballot was read incorrectly, in all orientations, even ballots that had read correctly just before lunch,” the ES&S report said.
