  • Takoma Park 2009: the conclusion

    Well, it’s been a few weeks of craziness at home and catching up on other work, but I’ve finally wrapped up the Takoma Park 2009 audit. The final step: letting you, dear reader, run the audit all on your own. You’ll find the complete instructions here on the auditing site. I haven’t tested this on […]

  • Takoma Park: verifying the shuffle and the unopened ballots

    So the votes have been cast, the uncertified tally has been released, and the confirmation codes have been published for all voters to check. Now, it’s time to make sure that the coded votes, which were shuffled via the Shuffle Tables into the decoded votes in the Results table, were indeed shuffled and decoded correctly. […]

  • Takoma Park: auditing the auditor

    Rick Carback from the Scantegrity team just pointed out to me that my totals are not quite the same as theirs, and he surmises that I may have read the Instant Runoff rules incorrectly. Specifically, my code considers that ballots that skip a rank, i.e. that go directly to choice #2 and never indicate a […]

  • Takoma Park: and those provisional ballots?

    Coverage of the Takoma Park election continues, with a good article in Wired. And so does the audit! Some people who showed up on election day couldn’t be verified as registered voters. Thanks to one of the useful HAVA provisions, they got to vote provisionally, meaning their ballot was set aside in an envelope labeled […]

  • Takoma Park: so can I see my confirmation code already?

    [This post is part of my Auditing the Takoma Park Municipal Election series.] So the votes have been cast, and voters went home. Some of them wrote down their confirmation codes. They probably checked those codes against the official Scantegrity web site. But why would they trust that web site to do all of the […]

  • Takoma Park 2009: Verifying the Tally from the Confirmation Codes

    [This post is part of my Auditing the Takoma Park Municipal Election series.] We’ll now consider the auditing portion of the Takoma Park election. This is a little bit involved, so we’ll take our time. Importantly, the typical voter does not need to burden themselves with this complexity. All that Valerie, our voter, needs to […]

  • Takoma Park 2009: the voter experience

    For background on this post, check out the Auditing Takoma Park 2009 Election. I’m gathering all documentation on a Google Site. This blog will continue to serve as the narrative, while the datasets and documentation will live on the Google Site, and I’ll refer to them as needed from this blog. Let’s begin with an explanation of the voting process that Takoma Park citizens will experience on November 3rd, 2009. (If you’re a Takoma Park resident: make sure to register by October 5th if you want to participate in this historic election!) Say hello to Valerie, our token voter. At a high level, Valerie’s voting experience is identical to her past experience with a typical optical-scan election. She fills in the bubbles for the candidates of her choice, casts her ballot, and walks away. With one twist: if Valerie wants to, she can write down some confirmation codes that will let her audit her ballot later on.
