Were software patches that didn't fix problems but instead changed results applied to electronic voting machines in two Georgia counties? Were the patches applied at the instruction of a top Diebold executive, without informing local election officials? This charge has been leveled several times since a rather surprising election in which two Democratic candidates had comfortable leads in polls just before Election Day yet lost by substantial margins. Of course, there's a strong correlation between your degree of suspicion of those results and which party you support. But we should all be frightened if there's no way to prove that tampering didn't occur. And when voting machines are electronic, paperless and proprietary, it's all but impossible to do a recount or check for errors in a way that can uncover a malicious hack. Election consultant Chris Hood told Rolling Stone magazine that he was working for Diebold in Georgia in 2002 when the head of the company's election division arrived to distribute a patch to workers. That code was applied to only about 5,000 machines in two counties. Hood says it was an unauthorized patch that was kept hidden from state officials. The Georgia allegations are disturbing but, sadly, not unique. An attorney and IT security consultant last month cited that incident to renew challenges to 2004 Ohio elections, which had a similar mix of paperless Diebold machines and statistically curious results.
