But sometimes, no original or additional commentary is needed, when someone says something pure and righteous. Like Paul Krugman's latest piece, his idea of the Great American Novel:
I've been thinking of writing a political novel. It will be a bad novel because there won't be any nuance: the villains won't just espouse an ideology I disagree with - they'll be hypocrites, cranks and scoundrels.
In my bad novel, a famous moralist who demanded national outrage over an affair and writes best-selling books about virtue will turn out to be hiding an expensive gambling habit. A talk radio host who advocates harsh penalties for drug violators will turn out to be hiding his own drug addiction.
In my bad novel, crusaders for moral values will be driven by strange obsessions. One senator's diatribe against gay marriage will link it to "man on dog" sex. Another will rant about the dangers of lesbians in high school bathrooms.
In my bad novel, the president will choose as head of homeland security a "good man" who turns out to have been the subject of an arrest warrant, who turned an apartment set aside for rescue workers into his personal love nest and who stalked at least one of his ex-lovers.
In my bad novel, a TV personality who claims to stand up for regular Americans against the elite will pay a large settlement in a sexual harassment case, in which he used his position of power to - on second thought, that story is too embarrassing even for a bad novel.
In my bad novel, apologists for the administration will charge foreign policy critics with anti-Semitism. But they will be silent when a prominent conservative declares that "Hollywood is controlled by secular Jews who hate Christianity in general and Catholicism in particular."
In my bad novel the administration will use the slogan "support the troops" to suppress criticism of its war policy. But it will ignore repeated complaints that the troops lack armor.
The secretary of defense - another "good man," according to the president - won't even bother signing letters to the families of soldiers killed in action.
Last but not least, in my bad novel the president, who portrays himself as the defender of good against evil, will preside over the widespread use of torture.
How did we find ourselves living in a bad novel? It was not ever thus. Hypocrites, cranks and scoundrels have always been with us, on both sides of the aisle. But 9/11 created an environment some liberals summarize with the acronym Iokiyar: it's O.K. if you're a Republican.
The public became unwilling to believe bad things about those who claim to be defending the nation against terrorism. And the hypocrites, cranks and scoundrels of the right, empowered by the public's credulity, have come out in unprecedented force.
Apologists for the administration would like us to forget all about the Kerik affair, but Bernard Kerik perfectly symbolizes the times we live in. Like Rudolph Giuliani and, yes, President Bush, he wasn't a hero of 9/11, but he played one on TV. And like Mr. Giuliani, he was quick to cash in, literally, on his undeserved reputation.
Once the New York newspapers began digging, it became clear that Mr. Kerik is, professionally and personally, a real piece of work. But that's not unusual these days among people who successfully pass themselves off as patriots and defenders of moral values. Mr. Kerik must still be wondering why he, unlike so many others, didn't get away with it.
And Alberto Gonzales must be hoping that senators don't bring up the subject.
The principal objection to making Mr. Gonzales attorney general is that doing so will tell the world that America thinks it's acceptable to torture people. But his confirmation will also be a statement about ethics.
As White House counsel, Mr. Gonzales was charged with vetting Mr. Kerik. He must have realized what kind of man he was dealing with - yet he declared Mr. Kerik fit to oversee homeland security.
Did Mr. Gonzales defer to the wishes of a president who wanted Mr. Kerik anyway, or did he decide that his boss wouldn't want to know? (The Nelson Report, a respected newsletter, reports that Mr. Bush has made it clear to his subordinates that he doesn't want to hear bad news about Iraq.)
Either way, when the Senate confirms Mr. Gonzales, it will mean that Iokiyar remains in effect, that the basic rules of ethics don't apply to people aligned with the ruling party. And reality will continue to be worse than any fiction I could write.
Nothing I could add would be of any help here, this is just too perfect.
