Biography

Jamie Joyce, a Democratic Berkeley-based technologist, researcher and nonprofit founder, lost the November 3, 2026 election for California's 12th Congressional District to incumbent Lateefah Simon, also a Democrat. According to her Ballotpedia profile, she founded the Society Library nonprofit and has worked on government-transparency projects at the Internet Archive.[1][2][3]

Basic profile — the most important sourced facts we found.

Joyce was born in New Hampshire and now lives in Berkeley.[2] Her Ballotpedia Candidate Connection survey describes her as a "multidisciplinary expert, executive, and researcher living in Berkeley" who has led AI teams and been interviewed for a documentary on artificial intelligence.[1] Before her work in technology, she says, she oversaw environmental and humanitarian projects with vulnerable communities in more than 20 countries, and Ballotpedia lists her as chief operating officer of the international organization IDEAS For Us.[1][2]

Joyce founded the Society Library nonprofit and co-founded the Canonical Debate Labs research group, and Ballotpedia lists her as program co-lead of the Internet Archive's Democracy's Library program.[1][2] She says she has spent nearly a decade building technology tools that help governments make policy decisions, including legislative drafting tools.[1] Ballotpedia also lists board and advisory roles at Wikitongues and Atlas Computing, a Collective Intelligence Fellowship from the Foresight Institute and an AI for Human Reasoning Fellowship from the Future of Life Foundation.[2]

Joyce advanced from the June 2, 2026 top-two primary, where she received 15.6% of the vote to Simon's 84.2%.[4][2] Her campaign centered on artificial-intelligence policy, government transparency, and a 650-page bill she had drafted, which she called the MAD Act.[1][2] She received 19.4% of the vote to Lateefah Simon's 80.6%, according to unofficial results reported by NBC News.[3]

In their own words

Priorities

  • Says she has drafted a 650-page bill she calls the MAD Act, which would strengthen dark-money disclosure requirements, place hard limits on surveillance, set guardrails on AI, and create accountability related to the Epstein network.[5]
  • Says she is working to build a bloc of 11 or more members of Congress who would withhold votes from legislation that does not serve voters first.[5]
  • Says she respects Rep. Simon's civil-rights and oversight work but believes the moment requires affirmative AI legislation and aggressive executive-branch oversight rather than incremental progress.[5]

Statements, quoted without a stance

  • Expand immigration enforcement and deportations
    “This bill pulls untrained ICE and CBP officers off our streets immediately while leaving officers who have been stationed in communities for years and who have clean records to continue their work dealing with human trafficking and truly criminal cases.”[6]

    On a fact sheet for her MAD Act (Title VIII), which her campaign site links as her bill

  • Continue U.S. military aid to Israel
    “Especially when their debt-to-GDP ratio suggests they can afford to maintain their own Iron Dome.”[7]
