The cashiering of "Brownie," whom Mr. Bush now purports to know as little as he did "Kenny Boy," changes nothing. The Knight Ridder newspapers found last week that it was the homeland security secretary, Michael Chertoff, not Mr. Brown, who had the greater authority to order federal agencies into service without any request from state or local officials. Mr. Chertoff waited a crucial, unexplained 36 hours before declaring Katrina an "incident of national significance," the trigger needed for federal action. Like Mr. Brown, he was oblivious to the humanitarian disaster unfolding in the convention center, confessing his ignorance of conditions there to NPR on the same day that the FEMA chief famously did so to Ted Koppel. Yet Mr. Bush's "culture of responsibility" does not hold Mr. Chertoff accountable. Quite the contrary: on Thursday the president charged Homeland Security with reviewing "emergency plans in every major city in America." Mr. Chertoff will surely do a heck of a job.

WHEN there's money on the line, cronies always come first in this White House, no matter how great the human suffering. After Katrina, the FEMA Web site directing charitable contributions prominently listed Operation Blessing, a Pat Robertson kitty that, according to I.R.S. documents obtained by ABC News, has given more than half of its yearly cash donations to Mr. Robertson's Christian Broadcasting Network. If FEMA is that cavalier about charitable donations, imagine what it's doing with the $62 billion (so far) of taxpayers' money sent its way for Katrina relief. Actually, you don't have to imagine: we already know some of it was immediately siphoned into no-bid contracts with a major Republican donor, the Fluor Corporation, as well as with a client of the consultant Joe Allbaugh, the Bush 2000 campaign manager who ran FEMA for this White House until Brownie, Mr. Allbaugh's college roommate, was installed in his place.

It was back in 2000 that Mr. Bush, in a debate with Al Gore, bragged about his gubernatorial prowess "on the front line of catastrophic situations," specifically citing a Texas flood, and paid the Clinton administration a rare compliment for putting a professional as effective as James Lee Witt in charge of FEMA. Exactly why Mr. Bush would staff that same agency months later with political hacks is one of many questions that must be answered by the independent investigation he and the Congressional majority are trying every which way to avoid. With or without a 9/11-style commission, the answers will come out. There are too many Americans who are angry and too many reporters who are on the case. (NBC and CNN are both opening full-time bureaus in New Orleans.) You know the world has changed when the widely despised news media have a far higher approval rating (77 percent) than the president (46 percent), as measured last week in a CNN/USA Today/Gallup poll.

Like his father before him, Mr. Bush has squandered the huge store of political capital he won in a war. His Thursday-night invocation of "armies of compassion" will prove as worthless as the "thousand points of light" that the first President Bush bestowed upon the poor from on high in New Orleans (at the Superdome, during the 1988 G.O.P. convention). It will be up to other Republicans in Washington to cut through the empty words and image-mongering to demand effective action from Mr. Bush on the Gulf Coast and in Iraq, if only because their own political lives are at stake. It's up to Democrats, though they show scant signs of realizing it, to step into the vacuum and propose an alternative to a fiscally disastrous conservatism that prizes pork over compassion. If the era of Great Society big government is over, the era of big government for special interests is proving a fiasco. Especially when it's presided over by a self-styled C.E.O. with a consistent three-decade record of running private and public enterprises alike into a ditch.

What comes next? Having turned the page on Mr. Bush, the country hungers for a vision that is something other than either liberal boilerplate or Rovian stagecraft. At this point, merely plain old competence, integrity and heart might do.

Op-Ed Columnist Correction: October 2, 2005, Sunday Op-Ed columns by Paul Krugman (Sept. 5 and 9), Maureen Dowd (Sept. 10) and Frank Rich (Sept. 18) said Michael Brown, the former FEMA director, was a college friend or college roommate of Joe Allbaugh, his predecessor. They went to different colleges and later became friends.
