He's still a liberal, but he is not of the socialist variety, and he loathes what greenpeace is today, he's more into science and the free market in his thinking, so he does sound conservative to alot of folks, for this he is often cursed and threatened.
He has also made some very interesting accusations against greenpeace over the years, that if true, should warrant a federal investigation.
I have followed him too. It is wonderful he has used reason too perceive the "truth" about environmental issues. He main theme in speeches is how Greenpeace and org like that are anti-Capitalist. It is good he is on our side. Greenpeace are a bunch of freaks. The environmental movement is at it's core totalitarian and truly damaging to the environment.
