Who They Are
The Ethanol Industry. A $35+ billion annual industry built on a government mandate: the Renewable Fuel Standard (RFS) requires petroleum refiners to blend 15+ billion gallons of corn ethanol into the U.S. fuel supply annually. This mandate — the most consequential agricultural subsidy in American history — diverts 40% of the U.S. corn crop into fuel production, supporting corn prices, ethanol producer revenue, and the entire Iowa/Midwest agricultural economy.
The industry’s political operation is channeled through the Renewable Fuels Association, Growth Energy, and the American Coalition for Ethanol — collectively spending $5-10 million annually on lobbying, plus significant political contributions through agricultural PACs. The ethanol lobby’s power is concentrated in Iowa — the first-in-the-nation caucus state where ethanol support is a prerequisite for presidential candidates of both parties.
What They Want
Preservation of the Renewable Fuel Standard, expansion of E15 (15% ethanol blend) sales year-round, favorable treatment in carbon intensity calculations, continued corn subsidy support, and opposition to electric vehicle mandates (which would reduce gasoline/ethanol demand).
What They’ve Gotten
The Renewable Fuel Standard: The RFS (2005, expanded 2007) is the ethanol industry’s structural foundation — a federal mandate that guarantees 15+ billion gallons of annual corn ethanol demand regardless of market conditions. The mandate transfers $7-10 billion annually from petroleum consumers (who pay higher fuel prices) to corn growers and ethanol producers (who receive guaranteed demand). The RFS has survived every attempt at repeal because Iowa’s first-in-the-nation caucus status forces presidential candidates of both parties to pledge ethanol support.
The Iowa Caucus Protection Racket: No presidential candidate has won the Iowa caucus while opposing ethanol. The caucus calendar position creates a structural requirement: every serious presidential candidate must pledge support for ethanol mandates to compete in Iowa. This calendar protection has preserved the RFS through administrations of both parties, despite the mandate’s questionable environmental benefits (lifecycle analysis shows marginal emissions reduction) and its contribution to food price inflation (diverting 40% of corn production).
Money
The ethanol mandate is the most efficient agricultural subsidy in American history: a government requirement that 40% of the corn crop become fuel, guaranteeing $35+ billion in annual industry revenue through regulatory fiat rather than appropriations. The $5-10 million annual lobbying investment protects a mandate worth hundreds of times more. The Iowa caucus provides the structural enforcement mechanism: any politician who opposes ethanol cannot win the presidency. The mandate’s costs — higher food prices, marginal environmental benefits, water pollution from corn agriculture — are distributed across all consumers, while the benefits are concentrated in the corn belt states that control the presidential primary calendar.
