What does passage mean? (It was interesting, watching Sec. Johanns at the National Press Club on one C-SPan channel while the final votes on the farm bill were happening on the other.)
What does it mean? For a bureaucrat, not too much. Theoretically, when both House and Senate had passed bills, you knew the boundaries of the world you had to plan for. That's because the conferees are supposed to compromise the differences between the two bills and are not supposed to create new provisions. But the reality was a bit different. The new could always happen in conference.
I can't even write that a change in payment limitation provisions is now certain. Likely, I'd say but the cotton and rice states have some powerful voices in the Senate.
