Methodology — LVMPD Info

Data sources

Nevada Secretary of State Aurora — campaign-finance filings (cf_candidates, cf_contributions, cf_expenditures, cf_groups, cf_reports). 9,074 candidates, 762,763 contributions across 2006–2026. Public records under NRS 294A.
NELIS (Nevada Legislature) — bill metadata, sponsorship, roll-call votes, hearing exhibits for the 83rd (2025) Session. Public records.
Ballotpedia — biographical context, salary, education, military service, predecessor, prior offices, social media. Cited per page.
NPE auditor pipeline — Tier-A through Tier-E detector outputs (PERS revolving-door, quid-pro-quo chains, recusal-failure findings, state-contractor donor patterns, donor concentration). See NPE methodology for the underlying detector rules.
Cloudflare Web Analytics — aggregate, anonymous traffic metrics. No tracking cookies. No third-party JS beyond the Cloudflare beacon.

Officeholder selection

The "current officeholder" for each office is selected via SQL on cf_candidates joined to cf_contributions:

ROW_NUMBER() OVER (PARTITION BY office
                  ORDER BY MAX(contribution_date) DESC NULLS LAST,
                           SUM(contribution_amount) DESC,
                           candidate_id DESC)

Most-recent-fundraising activity is the strongest signal of "currently in office" for non-legislator roles. State legislators are filtered separately via vote_count > 0 in the 83rd Session NELIS roll-call dataset.

Accountability research leads vs. allegations

Every flag on every page is a research lead, not an allegation. The auditor pipeline detects statistically-suspicious patterns (correlations between contributions and bill votes, name-matching between officeholders and the PERS pension database, etc.). A flag means "this warrants further investigation," not "this person did anything wrong."

Frameworks cited per flag type:

PERS revolving-door — NRS 286 (Nevada Public Employees Retirement System) + NRS 281A (public-officer ethics).
Quid-pro-quo chains — NRS 281A.420 (conflict-of-interest) + NRS 218H (lobbying disclosure) + NRS 294A (campaign finance).
Recusal-failure findings — NRS 281A.420 conflict-of-interest framework. Bills where a politician voted AND a campaign-contributing client testified.
State-contractor donors — NRS 333 (state purchasing) + NRS 218H (lobbying) + NRS 294A (campaign finance).
Donor-base concentration — DOJ Herfindahl-Hirschman Index "highly concentrated" threshold (HHI > 0.25), borrowed from antitrust jurisprudence and applied to political-donor concentration.

Update cadence + freshness

Politician profiles regenerate from upstream sources on a nightly cron on workstation (3:30 AM Pacific). Each profile carries a data_quality.last_verified timestamp. Stale profiles (last_verified > 120 days) display a "stale verification" banner.

Sitemaps are submitted to IndexNow (Bing + Yandex) on every successful rebuild. Cloudflare cache is purged for changed paths.

Editorial discipline (non-negotiable)

Every claim cites a public-record source. Every page footer lists references.
No editorial framing. The same facts render the same way on the bipartisan master and the party-themed portals — only the brand color and party-filter differ.
No PII beyond official: office contact info yes, home addresses no.
US-only compliance: ADA, Section 508, FOIA, FTC Act, CAN-SPAM, COPPA, US copyright, Nevada state law. No GDPR / EU regulatory artifacts.
Photos: self-hosted only. No hot-linking. Where Ballotpedia provides a thumbnail under their terms, we cache locally and credit per the references list.
