New Jersey congressman Chris Smith has represented his state for more than 25 years and has been talking about global warming for nearly as long, sponsoring his first global warming-focused legislation in the late '80s. He's a member of the exclusive club of Republicans who have received the endorsement of the League of Conservation Voters and he earned a rating of 77 percent for 2008. This year, Congressman Smith voted for the American Clean Energy and Security Act, only one of a handful of Republicans to do so. Perhaps most surprising, he cited the sound science behind climate change as a reason — he's no cherry-picking denier.
