Kevin Drum, probably the blogger whose views most coincide with mine, or rather vice versa, says that Republican farm policy makes perfect sense.
[edited to add]
I follow the Volokh Conspiracy, which just posted on the farm bill: crop insurance versus SNAP cuts issue. I sometimes comment there, but I'm abstaining this time. There's too much wrong and incomplete information there, probably because it's mostly a bunch of "city folk", as my mother would say.
