One of the few Congressmen willing to stand up to the Farm Lobby is Arizona's Jeff Flake.
I think he got his metaphors confused in this remark reported by The Prince Of Darkness, Robert Novak.
(Paul) Ryan's fellow reformer, 45-year-old Jeff Flake of Arizona, in his fourth term, is less cautious about defying the leadership and has been kept off key committees. On Wednesday, he said of a $300 billion bill that raises farm subsidies and is filled with non-farm pork, "Sometimes, here in Washington, we tend to drink our own bath water and believe our own press releases."
However admirable Congressman Flake's policies may be, I believe "bath water" is not what Congress drinks, but is what Congress throws babies out with. The "Kool Aid" is what Congress persuades foolish voters to drink. It's a reference to Jim Jones poisoning his followers in Guyana.
