Americans are more divided today than at any time since the Civil War. Our differences are not merely moral and political, but philosophical, and even spiritual. We hardly seem to experience the same reality anymore, preferring to self-select into media perception chambers whose projections vary according to political persuasion.

Something has gone terribly wrong in the American political community. We have entered an era wherein the federal government's democratically elected officers are powerless in comparison to their unelected, bureaucratic counterparts. The old balance of power, laid out in the Constitution, has been replaced by an entirely new structure.

The American regime has become post-constitutional. But what is this post-constitutional arrangement? How does it operate? Who is in charge?Can it be overcome? What role will the Constitution play in the nation's future?

Glenn Ellmers-senior fellow with the Claremont Institute, widely-published analyst of current affairs, and scholar of political philosophy-provides answers to these and other questions, as he explores the deepest roots of our political turmoil, illustrating the connections between government bureaucracy, the misuse of science, and the leftwing ideology that controls so much of our public and private life.
