This chapter examines the politics surrounding policy drifts in the area of climate change. In particular, it focuses on one critical, contemporary policy drift: the Clean Power Plan, a historic and important step in reducing global warming. A host of policy players, particularly individual states, are stakeholders in the process as well as outcomes. As will be seen, shared beliefs and values led policy players to form advocacy coalitions. These coalitions, consisting of state governments and their allies (i.e., business and fuel interest groups), fight for certain values, and work against those coalitions that oppose them.
