Ryan Sager: "My theory of why no one in politics likes to think about political science: because it renders them powerless. How do you do your job as a political consultant when the truth is that 90% of the success or failure of what you do will be determined by the unemployment rate? ... The point is, we need to believe we're in control. Political science tells everyone in politics the opposite: You're not in control. The economy rules your fate -- the rest is just pissing in the wind."
