I think the similarity is with initiative 72, which was revenue neutral. I think the effort you're making with the federal backstop is an effort to be revenue neutral for folks.
Again, that failed in Washington state for a couple of reasons: first, people didn't trust that the deal would stick; and second, the environmental community ironically opposed it, because they wanted a revenue increase.
Those were the primary concerns that are similar to what you're trying to do, in our experience.
