As Noah noted earlier, the House of Representatives is at long last scheduled to vote on the Waxman-Markey climate-change bill today. Take a deep breath, everyone. This is a marathon, not a sprint. Depending on who you talk to, it’s likely to pass, likely to fail or still up in the air. And depending on what you read, it’s an imperfect bill that should pass, a fatally flawed bill that should fail or a bad idea from the start; it will either kill the U.S. economy or create jobs; and it either goes too far or it not far enough.
