Ethanol's pros and cons

How much does an x
% ethanol gasoline blend product reduce mileage? Does the environmental benefit from ethanol blends outweigh the increased consumption of gasoline products? Or is the benefit negligible for the consumer?

Though ethanol burns cleaner, it apparently holds less chemical energy for the same volume. After noticing local gas stations selling (only) 10% ethanol blends at higher prices, I'm curious about how much of an effect this has on mileage. Most of the information I've found (from corn growers) is handwaving, inconclusive or apologetic.
After all, if the fuel burns faster and costs more, and the ethanol supply is subsidized, that means more frequent and profitable repeat business for energy suppliers and corn growing-conglomerates like ADM.
Further, more frequent trips to the gas station mean increased emissions for the same energy dollars spent in the country.
Also, I imagine that ethanol corrosion also means more dollars spent on parts replacement and labor in the automobile maintenance industries, which also has a waste impact on the environment (more stuff put into landfills at a faster rate).
Do the ethanol products have a genuine and pronounced net benefit to the environment or is this about profit for energy, agribusiness and automobile corporations?
