Ethanol Mandate for Iowa?

"sfb" writes:

There are two sets of subsidies at play. From 1995 to 2003, corn was
subsidized to the tune of $37 billion dollars. Ethanol subsidies are tax
credits and loan guarantees to build plants. Unless or until the Federal
corn program can differentiate corn grown for feed or food vs. ethanol,
corn for ethanol is subsidizied.

That's why the statement "A farmer cannot make a profit from selling the
corn outright to an ethanol producer" still confuses me. Perhaps I'm not
getting all of the implications behind "outright"? Or perhaps "to an
ethanol producer" was just misleading/superfluous?

So...do we get to talk about the billions of dollars subsidizing oil
production?
