This email from the Secretary of State of Washington outlines another bug in the new IRV voting system for Pierce County. It affects "rank choice voting" (IRV/Instant Runoff) only. Pierce County Washington adopted "instant runoff voting" in November 2006. In May 2008, officials were backed into a corner and ended up getting permission to use uncertified IRV software, violating their own state's laws.
Pierce county has Sequoia "Insight" optical scanners and DREs. The tabulating software, WinEDS 4.0.34 is still under test by iBeta. There is not even a test plan presented to the EAC for this system at this time. Washington State provisionally certified this software for use even after finding that there were problems with the use of the Insight machines when used in the RCV process. San Francisco is also using this system, and currently it is not certified in California to count IRV. San Francisco officials still don't know how they will count their "ranked choice" voting in November 2008.
Here's the email (Thanks to John Gideon of www.VotersUnite.org for sharing)
It has come to our attention that there is a very rare occurrence of a problem with the Rank Choice Voting results loading with Pierce County’s provisionally certified software.
