To those millions of Americans who have finally begun paying attention to politics and watched with exasperation the tragicomedy of the debt ceiling extension, it may have come as a shock that the Republican Party is so full of lunatics. To be sure, the party, like any political party on earth, has always had its share of crackpots, like Robert K. Dornan or William E. Dannemeyer. But the crackpot outliers of two decades ago have become the vital center today: Steve King, Michele Bachman (now a leading presidential candidate as well), Paul Broun, Patrick McHenry, Virginia Foxx, Louie Gohmert, Allen West. The Congressional directory now reads like a casebook of lunacy.

When I was a congressional staffer, I became acutely aware that elected officials choose issues to put at the top of their agendas mainly for their ability to shake money out of the purses of contributors. The subsequent histrionics in the House or Senate chamber are pure theater for the benefit of C-SPAN and the poor recluses who watch it. Behind every political cause is a racket designed to privatize the profits and socialize the losses.

It is difficult to read Pay Any Price and not come away with the sick feeling that the Bush presidency—which, after all, only assumed office by the grace of judicial wiring and force majeure—was at bottom a corrupt and criminal operation in collusion with private interests to hijack the public treasury. But what does that say about Congress, which acted more often as a cheerleader than a constitutional check? And what does it tell us about the Obama administration, whose Justice Department not only failed to hold the miscreants accountable, but has preserved and expanded some of its predecessors’ most objectionable policies?

Partisans may squabble over the relative culpability of the Bush and Obama administrations, as well as that of Congress, but that debate is now almost beside the point. If Risen is correct, America’s campaign against terrorism may have evolved to the point that endless war is the tacit but unalterable goal, regardless of who is formally in charge.
