Changing the Conversation on Climate Change - Bloomberg
As in 2009, the main challenge will be in the Senate. Although a regulatory approach wouldn’t require positive congressional action -- or the 60 votes necessary to stop a filibuster -- it could be rescinded by a majority vote. Emissions rules might lose such a vote even in the present Democratic-controlled Senate. And if they survived -- especially if they survived thanks to a presidential veto -- they might only help ensure that the Democrats lose the Senate in 2014.
