In November 2018, Maine was first in the nation to use Ranked Choice Voting statewide in what turned out to be an incredibly transparent election. The Secretary of State live-streamed the candidate-elimination process, then posted Excel files of all the original ballot data.
Despite the transparency, CD2 incumbent Bruce Poliquin has charged RCV is a “black box” that somehow uses AI. To dispel these false notions, a couple citizen hacktivists independently created their own RCV election tabulators to verify the ultimate winner of the election, and then published their results. Bates professor Nathan Tefft was first to do so, soon followed by Scotty Vercoe, producer of the film The Battle for Ranked Choice Voting, who discovered a nuance unavailable in the official data.
Here, Scotty talks about writing code to verify the highly disputed election…
The thought that it’s some kind of AI is laughable. In reality, RCV can be implemented in a few lines of code, and only takes a split-second to run:
Although using a slightly different approach, I was able to arrive at the exact same results with my Python script as the Secretary of State’s office and Professor Tefft.
But here’s how mine finds the missing data! The Secretary of State’s office used “batch eliminations” based on their mathematical impossibility to win. While this arrives at the winning candidate correctly, we miss some of the drama along the way. It wasn’t until I used runoffs that I could see that candidate Tiffany Bond received a maximum of 6.67% support. This is completely missing from the Secretary of State’s published results, and an important aspect of this election! I’m sure Ms. Bond would agree.
