Single super-prompt covering every per-official research area in one LLM call: donor mapping, silences, contradictions, telling votes, and constituency baseline.

The median household income is $65,139 — well above the national median but below the Indiana metro average. The poverty rate is 13.4%, and only 23.2% of residents hold bachelor's degrees, significantly below the 33.7% national average. The population is 88.6% White (Non-Hispanic) with 98.5% U.S. citizenship — one of the highest citizenship rates of any congressional district. Only 2.5% of residents are foreign-born. The economy is anchored by healthcare (Deaconess Health System, ~10,500 employees), defense (Naval Surface Warfare Center Crane, 6,000+ employees), manufacturing, and agriculture (second most productive row-crop district in Indiana). The district has a median home value of $174,000 and a 72.3% homeownership rate. It is car-dependent with 80.2% driving alone to work and an average 22.8-minute commute.",
