Civic/Governance Barriers activates on moratorium-class action (C1), 2026 ballot measure (C2), meaningful 2026 race (C3) — governance instruments on the electoral, legislative, and regulatory surface (protocol §10; Overview Civic breakout). Capital Flows is a dominant stressor: the referendum directly constrains TIF financing for data centers, gubernatorial candidates campaign on 'ending subsidies,' AB 840 targets cost-shifting, and the PSC ruled against ratepayer subsidization — a cluster of financing/insurability signals (Daily Reporter, Urban Milwaukee). Energy/Power and Water/Geology drive the local moratoria.

Open 2026 governor's race (Gov. Evers not running) has made data centers a defining, party-blurring issue. Democrats Francesca Hong and Joel Brennan back a construction pause; Barnes, Rodriguez, Crowley, Roys and Hughes favor tighter regulation/local veto; Republican Tom Tiffany vows to 'end subsidies' (Daily Reporter).

Local moratoria and a first-in-nation referendum. Madison enacted a one-year temporary ban on data centers over 10,000 sq ft (Jan. 2026) (Madison Legistar). Dane County adopted an 18-month hyperscale moratorium unanimously (~June 8, 2026), sent to County Exec Melissa Agard (WisBusiness). No statewide moratorium: Rep. Darrin Madison's 'Pause to Protect Act' failed Mar. 23, 2026 (WisPolitics).

AB 840 (Rep. Zimmerman, R), a ratepayer/cost-shift bill, passed the Assembly 53-44 on Jan. 20, 2026 but stalled in the Senate (Milwaukee Journal Sentinel). The WI Public Service Commission ruled (~May 2026) that existing customers should not subsidize data centers.

Two consequential 2026 cycle measures. (1) Port Washington referendum PASSED Apr. 7, 2026 (~66%), requiring voter approval of TIF districts over $10M; it does not unwind the existing $458M Vantage TID and faces a business-group legal challenge (MMAC) (Milwaukee Journal Sentinel, The Hill). (2) Janesville Require Voter Approval for Development of GM/JATCO Site Exceeding $450 Million Initiative is on the Nov. 3, 2026 municipal ballot — citizen petition certified (~3,927 signatures); City Council placed it Feb. 9, 2026 after opposition to a proposed ~800 MW / ~$8B Viridian Partners data-center reuse of the former GM plant (LOI later allowed to lapse) (Ballotpedia), Milwaukee Journal Sentinel).

Vantage 'Project Lighthouse' $15B campus (Oracle/OpenAI) in Port Washington broke ground Dec. 17, 2025 and is the epicenter of the referendum fight; Microsoft's Caledonia (244-acre) project was WITHDRAWN Oct. 8, 2025 after community pushback (Milwaukee Journal Sentinel — Caledonia).

Construction-jobs promises feature in project debates but no distinct labor-organizing or AI-displacement storyline dominates; not a primary lens this cycle.

Growing cluster anchored by the $15B Vantage Port Washington campus and Microsoft's Mount Pleasant/Racine-area investment, with contested projects across Ozaukee and Dane counties (The Hill).

Republican gubernatorial candidate Tom Tiffany has said he would move to 'end subsidies' for data centers (Daily Reporter).
