I don't think that highly of McCain. I was mad over the McCain-Feingold bill. And when he jumped on the global warming bandwagon, that just made him fall even further in my opinion.
I listened to Senator Orrin Hatch on the Lars Larson radio show last night. He very politely said that he disagreed with McCain on a number of issues, specifically the one you mentioned. I don't think Hatch thinks that McCain is very conservative. But he said it in a diplomatic way. He was really a pleasure to listen to.
