San Francisco is expected today to extend a voting machine contract for two years, even as The City plans to switch over to an open source voting system. An update on those open source voting plans are expected to be provided during the upcoming budget process before the Board of Supervisors later this year as the board is expected to approve the extension today. In the meantime, John Arntz, director of the Elections Department, said The City needs to extend the contract with Dominion, formerly known as Sequoia Voting Systems, Inc., for the two scheduled upcoming elections in 2018 – the Statewide Primary Election on June 5, 2018, and the General Election on Nov. 6, 2018. The two-year contract extension from Dec. 11, 2016 through Dec. 31, 2018, totals $2.3 million, for a total of $21 million since The City first entered into an agreement with the voting machine company in 2007 through a competitively bid process. There is also a chance there may be a special November election through a local signature gathering effort.
