South Dakota's U.S. Senate candidates show a wide range of positions on the government's role in energy development.
Democrat Rick Weiland says big oil has been writing the nation's energy policy, and until that changes it's going to be difficult to develop a smart policy for the people and the planet.
Republican Mike Rounds says government should encourage all energy development, and that includes coal and domestic oil as well as alternative sources such as ethanol, biodiesel and wind.
Independent Larry Pressler says the country should develop a long-term strategy to move toward environmentally friendly energy sources, but it will need oil and coal in the near-term.
Independent Gordon Howie says the government should allow the free market to determine what works and let businesses try to make a profit.
