The NYT's David Brooks picks up a thread from a blogger (in addition to building on an earlier column) an asks whether the Hurricane Katrina disaster will trigger a major political shift in the U.S.

Some excerpts:

As Ross Douthat observed on his blog, The American Scene, Katrina was the anti-9/11.

On Sept. 11, Rudy Giuliani took control. The government response was quick and decisive. The rich and poor suffered alike. Americans had been hit, but felt united and strong. Public confidence in institutions surged.

Last week in New Orleans, by contrast, nobody took control. Authority was diffuse and action was ineffective. The rich escaped while the poor were abandoned. Leaders spun while looters rampaged. Partisans squabbled while the nation was ashamed.

The first rule of the social fabric - that in times of crisis you protect the vulnerable - was trampled. Leaving the poor in New Orleans was the moral equivalent of leaving the injured on the battlefield. No wonder confidence in civic institutions is plummeting.

And the key fact to understanding why this is such a huge cultural moment is this: Last week's national humiliation comes at the end of a string of confidence-shaking institutional failures that have cumulatively changed the nation's psyche.

Over the past few years, we have seen intelligence failures in the inability to prevent Sept. 11 and find W.M.D.'s in Iraq. We have seen incompetent postwar planning. We have seen the collapse of Enron and corruption scandals on Wall Street. We have seen scandals at our leading magazines and newspapers, steroids in baseball, the horror of Abu Ghraib. ...

Reaganite conservatism was the response to the pessimism and feebleness of the 1970's. Maybe this time there will be a progressive resurgence. Maybe we are entering an age of hardheaded law and order. (Rudy Giuliani, an unlikely G.O.P. nominee a few months ago, could now win in a walk.) Maybe there will be call for McCainist patriotism and nonpartisan independence. All we can be sure of is that the political culture is about to undergo some big change.

We're not really at a tipping point as much as a bursting point. People are mad as hell, unwilling to take it anymore.
