"Black Box Voting has taken the position that fraud took place in the 2004 election through electronic voting machines. We base this on hard evidence, documents obtained in public records requests, inside information, and other data indicative of manipulation of electronic voting systems. What we do not know is the specific scope of the fraud. We are working now to compile the proof, based not on soft evidence -- red flags, exit polls -- but core documents obtained by Black Box Voting in the most massive Freedom of Information action in history."
