Government queries split into six retrieval patterns. Regulation and rule-making queries ("is the new EPA rule final," "what does the FTC noncompete order say," "DOL overtime threshold") route to the Federal Register, agency rule-making pages, regulations.gov, and the political press as secondary attribution.
Legislation and policy queries ("what is the Inflation Reduction Act," "text of the AI Executive Order," "CHIPS Act provisions") route to Congress.gov, CRS reports, White House documents, and Wikipedia.
Federal-spending and budget queries ("defense budget 2026," "Medicare spending growth," "federal deficit projection") route to CBO, OMB, GAO, and the political press.
Agency-operations queries ("DHS cybersecurity modernization," "SBA loan program changes," "VA budget growth") route to agency websites, Government Executive, Federal News Network, FedScoop, NextGov, and the political press.
State and local government queries ("California minimum wage law," "Texas water rights," "NYC congestion pricing status") route to state government sites, StateScoop, Route Fifty, GovTech, and local press. Political-news queries ("Senate confirmation status," "presidential approval trends," "caucus alignment") route to Politico, The Hill, Axios, Roll Call, and broader political press.
Cross-engine variation: ChatGPT and Claude weight Federal Register, CRS reports, and Brookings institutionally. Perplexity surfaces Politico and Axios aggressively. Google AI Overviews favors Wikipedia and the agency websites on policy and program-explainer queries.
Geographic dispersion: U.S. federal documents are central to English-language government retrieval. UK government press (BBC News politics, Politico Europe, Reuters UK) reaches U.S. engines well. Continental EU policy press (Euractiv, Politico Europe) reaches at moderate frequency. Most other national-government retrieval is fragmented in English-language engines.
GEO implication for agencies, lobbyists, public-affairs operators, and government contractors. The retrieval levers are agency-document accuracy (most agencies have never audited how their own publications appear in AI retrieval), CRS and GAO citation visibility, think-tank publication participation, and political-press coverage for narrative positioning. For contractors and trade associations, FedScoop and Government Executive coverage carries the procurement-class queries.
