Okay this is 15 years old (and YES it is from the Cato Institute-that should tell you how bad it is)
Archer Daniels Midland:
A Case Study In Corporate Welfare
September 26, 1995
ADM has cost the American economy billions of dollars since 1980 and has indirectly cost Americans tens of billions of dollars in higher prices and higher taxes over that same period. At least 43 percent of ADM's annual profits are from products heavily subsidized or protected by the American government. Moreover, every $1 of profits earned by ADM's corn sweetener operation costs consumers $10, and every $1 of profits earned by its ethanol operation costs taxpayers $30

Ethanol producers receive an array of subsidies from federal and state governments. The largest subsidy is the exemption from federal fuel taxes. Gasoline companies receive a tax break of 5.4 cents for each gallon of gasohol they sell. Because gasohol is usually sold in a mixture of nine parts gasoline to one part ethanol, each gallon of ethanol receives the equivalent of a 54 cent break from the federal tax code. While it is often misleading to speak of tax deductions and credits as the equivalent of a direct federal subsidy, it is certainly the case that, without the massive distortion of the tax code, there would be no ethanol industry, given the large cost differential in the production of ethanol and traditional gasoline.
Ethanol subsidies reduce federal revenues by $770 million a year,(30) losses that the Congressional Research Service estimates could rise to $1 billion by the year 2000.(31) Many state governments also heavily subsidize the production or use of ethanol.(32)
