While the Sustainable Agriculture Coalition often takes positions with which I have some problems, they seem almost always to do a good and detailed job of summarizing what's happening on the Hill. Rather than resummarize what happened when the House passed the ag appropriations bill, see their summary.
Just two things I'd mention: one is the obvious--this vote means little, the real action will be how the conference committee reconciles House and Senate bills (assuming there ever is one) particularly the paying Brazil $147 million for cotton program bit). The other is the fact that the USDA building and facilities fund was raided for other purposes. No one worries about how the bureaucrats are housed.
