From a post by Michael Alvarez at CalTech’s Elections Updates:

As Election Updates readers know, in 2018 our Caltech team collaborated in an important election integrity and election performance auditing study with the Orange County Registrar of Voters. The project material is available online — and we are now working on various research papers and a book-length report about the pilot project, how we did it, what we found, and how we can improve on these methods in the future.

In an interesting development, Orange County will be moving away from traditional Election Day polling place voting, towards more widespread use of voting by mail and vote centers. Here’s an OC Registrar story that talks about the transition.

We are looking forward to the continuation of our collaboration with OCROV, and helping them as they implement and evaluate this transition in 2020. The data and analyses that we did in 2018 will provide strong baseline data that we can use to evaluate the changes in 2020, and there’s no doubt that the results of our continued collaboration will provide important data for other jurisdictions that are planning on similar transitions in the near future.
