Seventeen days ago, The Politico ran a blog item about John Edwards getting a $400 haircut. As you no doubt recall, it made the rounds extraordinarily quickly, even generating a question at last week’s debate. By and large, there’s not much more to say about it; the “news” angle has been relegated to the late-night comedians.

That is, except for The Politico’s top political columnist, Roger Simon, who devoted his column to the subject today.

It is the haircut that will not die.

He can spin it, he can gel it, he can mousse it. But it is not going away.

John Edwards’ $400 haircuts will live forever.

The column has a wonderful circular quality to it. Simon is thinking about it, Simon is writing about it, so therefore Simon believes the story continues to be fascinating. He must be right because, lo and behold, there’s a 660-word column on the subject, 17 days later, right there on The Politico.

Fortunately, Glenn Greenwald took Simon to task.
