[Washington Post] "It's not fair, it isn't working and it doesn't serve a purpose." That pithy judgment, by Mexican President-elect Vicente Fox, is of the annual process the United States uses to certify whether Mexico and other drug-producing countries have "cooperated fully" in the fight against drugs. His judgment is right, and the administration may even agree; certainly Gen. Barry McCaffrey, the national drug control policy director, has said much the same. But so far, Congress has fiercely resisted any change, because the present situation serves U.S. party politics too well.
