Actually, they should be more concerned about alignment with the Constitution.
Power or control over agriculture not being one of the enumerated powers of congress or any other branch of the central government and not a power delegated to the United States by the Constitution is therefor reserved to the states or the people by the tenth amendment:
"The powers not delegated to the United States by the Constitution, nor prohibited by it to the States, are reserved to the States respectively, or to the people."
Agree 100%. And their function for Agriculture is all about power and control.
Their most important function now is “food stamps” and related food programs. Most of their budget goes to that and that is what most of the work force at the Department of Ag. does.
What they do to farmers is regulation after regulation and enforcement of regulation. Forcing tons of paperwork and nonsense tasks on farmers and ranchers. They do very, very little in the way of help. Not worth it, and as you say not constitutional.
