"A Politicized Bush Justice Department": To prevent the abuse of the courts for political ends, the DOJ was traditionally the least-politicized of all the executive branch departments. That all changed when Bush took office. In 2007, Daniel Schulman was among the first to document how the conservative Federalist society may have influenced personnel decisions at the DOJ.
This is my pick because it will be with us for many years to come. There was nothing on there about the environment or that would have come first.
