You'd think we'd know what a farmer is; after all people have been farming for thousands of years.
But, here, via FarmPolicy at Sen. Grassley's website, is the latest GAO report on FSA enforcement of the rules.
I remember the people (WP and SN) originally developing the rules after the 1985 farm bill. Amazing to realize that they might well be grandparents by now. If I remember, the first crack at implementing the provisions got overridden by Congress. That sort of history is probably why FSA is saying they won't change rules now without having Congress act. Part of the problem is, once provisions are in the farm bill and passed, members' attention shifts elsewhere, so the members who are more responsive to their farmer constituents gain in influence.
