Does Big Ag run the whole country now?

From a pal in Iowa:

Per below, I and a couple of hundred other Iowans were flatly told two days
ago, at one of the most infuriating public meetings I've attended in thirty
years of meetings, that EPA efforts to regulate non-point ag pollution going
into the Chesapeake Bay "didn't work," period, and so only an all-voluntary
approach will work in Iowa. If looks could kill, the two guys who ran that meeting and
spun out most of the BS would be dead. I wasn't the only person who was
angry.
