Seems long overdue, but this is apparently the first year that national environmental groups are directing substantial campaign contributions into state-level races. Outfits like the Sierra Club and the League of Conservation Voters have traditionally made all their donations at the federal level, but are now realizing that much of the action is in state capitals. Surprise favorite: Arnold Schwarzenegger, a Republican who imposed caps on industrial greenhouse gases. OK, the guy has a pretty good record on the environment, but does he really need this help more than, say, Green Party candidates?
