goombah99 writes "Princeton Professor, Ed Felton, has posted a series of blog entries in which he shows the printed tapes he obtained from the NJ voting machines don't report the ballots correctly. In response to the first one, Sequoia admitted that the machines had a known software design error that did not correctly record which kind of ballots were cast (republican or democratic primary ballots) but insisted the vote totals were correct. Then, further tapes showed this explanation to be insufficient. In response, State officials insisted that the (poorly printed) tapes were misread by Felton. Again further tapes showed this not to be a sufficient explanation. However all those did not foreclose the optimistic assessment that the errors were benign — that is, the possibility that vote totals might really be correct even though the ballot totals were wrong and the origin of the errors had not been explained. Now he has found (well-printed) tapes that show what appears to be hard proof that it's the vote totals that are wrong, since two different readout methods don't agree. Sequoia has made trade-secret legal threats against those wishing to mount an independent examination of the equipment. One small hat-tip to Sequoia: at least they are reporting enough raw data in different formats that these kinds of errors can come to light — that lesson should be kept in mind when writing future requirements for voting machines."
