Well, after reading the other replies to this thread, I certainly feel foolish. I'm off to do some research and bring myself up to date on Pombo.
I seriously doubt that Dick Pombo is ignorant of where Arnold stands ideologically on environmental issues, but I don't know if he fully understands Arnold's affiliations with his backers. Frankly, I hope he doesn't and this is all just political posturing. I suspect you know that Arnold is deeply involved with the NRDC, primarily through his cousin-in-law Robert F. Kennedy Jr. In addition, Arnold's largest source of his opulent campaign money is large scale developers, such as Kaufmann & Broad http://www.arnoldwatch.org/assets/contributions_graph.gif, followed by Wall Street banks that just so happen to have "facilitated" massive bond sales to bail out a State on the brink of bankruptcy. He also has uncomfortably close affiliation with some rather unsavory gambling interests, not to mention substantial investments in hydrogen fuels.
