The 2006 elections seemed to have passed without major problems with the electronic voting machines, but here is the problem: We'll never know. Because these machines could be tampered with invisibly, there is simply no way to know if they were or not, because there is no audit trail. We simply have no way to check to see if vote counts were altered. We may have dodged a bullet this time, but these machines are problematic, and a threat to our country.
