Corruption Risk · 4-Vector Breakdown

Corruption isn't just trade-based. Here's the four ways political pressure can flow, scored independently from the public record.

📈 Vector 1 · Personal Enrichment trade-based
The politician's trading profile is defined by a severe performance anomaly: an overall win rate of 29% (`get_politician_intelligence.profile.win_rate_overall`) masks extreme sector divergences. In the energy sector, a 100% win rate (`get_politician_intelligence.sector_expertise[3]`) outperforms the overall rate by 71 points, with an average return of 10.76%. Similarly, infrastructure shows a 100% win rate. This contrasts with a 0% win rate in the consumer sector. Despite 490 trades in the 5-year analysis period (`get_politician_intelligence.profile.total_trades`), the activity is characterized as 'inactive' and 'passive or advisor-managed' (`get_sponsor_profile.profile.trade_pattern`), concentrated in a single stock (PG) and U.S. Treasuries, with a 29% win rate and a 'POOR_PERFORMER' style.

💵 Vector 2 · Donor Funding money in
Total PAC funding over 5 years is $27.89M (`get_donor_industry_breakdown.total_pac_direct_usd`), with top industries being corporate_other (33.3%), labor (9.7%), and healthcare (7.8%). Lobbying spend targeting the politician's committees totals $5.11M (`get_sponsor_profile.profile.total_lobbying_spend_5yr_usd`), but no matching filings indicate direct committee alignment (`get_lobbying_around_pol.matching_filings_count`). The industry capture signal is 'low' (`get_sponsor_profile.profile.industry_capture_signal`).

🏛 Vector 3 · Committee Pressure lobbying around
No single industry dominates via a clear quid-pro-quo mechanism; top PAC funding is a broad 'corporate_other' category at 33.3% of $27.89M (`get_donor_industry_breakdown.top_industries[0]`).
