According to Buck's campaign website, Buck is strongly opposed to the "cap and trade" bill that currently is in Congress. Buck says, "On this issue there couldn't be a bigger difference between the 'appointed' Senator Michael Bennet and me."
At the first set of debates between Buck and Bennet in Grand Junction, Colo. last week, the discussion about energy independence was heated. According to the National Review Online, at the debate, Buck asked Bennet about his support of cap and trade, and his response was, "I didn't support the cap and trade bill that passed in the House. And I do think it's an unproductive conversation to be fighting about cap and trade or carbon tax."
