Ex-EPA administrator (and N.J. governor) Christie Todd Whitman is somewhat of a mystery to progressives. She talks like a moderate, and even dares criticize the Bush junta, but she was complicit in the very hard right policies she now disavows -- and, conspicuously, didn't disavow them at the time. The question in the mind of many pundits is, "naive dupe or dishonest hack?" After reading Whitman's op-ed in the San Francisco Chronicle today arguing that we need "a new debate on the environment," I'm leaning toward hack.
