A new report by Common Cause and Verified Voting describe the scope of the problem. Six states are at high risk form machine errors the could change election results but have no audit trail or verification mechanism. Another 17 states are at risk from voting machine failures.

This story isn't just for conspiracy theorists any more. The report notes:

The contest for Florida’s 13th Congressional District in November 2006 is a recent example. In the final tally of this election, an extraordinarily high number of ballots in Sarasota County - 17,846 - showed no vote cast. But the race itself was decided by 369 votes. In other words, the undervotes could have changed the outcome of the race if they had been registered. The high undervote rate is all the more striking because it was approximately five times higher than the undervote rate in surrounding counties. The cause of this extraordinarily high undervote is not known for certain, but the evidence points to machine-related failure. Two lawsuits have ensued and the Government Accountability Office is conducting an investigation.

Now imagine changing the word "votes" to "dollars" and think of this as your financial management software instead of an e-voting machine. How long would you last in business?
