In the wake of the 2010 elections, President Obama declared that voters did not give a mandate to gridlock. His statement reflects over a century of Progressive hostility to the inefficient and slow system of government created by the American Framers. Convinced that the government created by the Constitution frustrates their goals, Progressives have long sought ways around its checks and balances. Perhaps the most important of their methods is delegating power to administrative agencies, an arrangement that greatly transformed U.S. government during and after the New Deal. For generations, Progressives have supported the false premise that administrative action in the hands of experts will realize the public interest more effectively than the constitutional system and its multiple vetoes over policy changes. The political effect of empowering the administrative state has been quite different: it fosters policies that reflect the interests of those with wellorganized power. A large and growing body of evidence makes it clear that the public interest is most secure when governmental institutions are inefficient decisionmakers. An arrangement that brings diverse interests into a complex, sluggish decisionmaking process is generally unattractive to special interests. Gridlock also neutralizes some political benefits that producer groups and other well‐heeled interests inherently enjoy. By fostering gridlock, the U.S. Constitution increases the likelihood that policies will reflect broad, unorganized interests instead of the interests of narrow, organized groups.
