In the 1700s, politics was all about the ideas. But Jefferson came up with all the good ideas. In the 1800s, it was all about character. But no one will ever have as much character as Lincoln and Lee. For much of the 1900s it was about charisma. But we no longer trust charisma because Hitler used it to kill Jews and JFK used it to get laid and send us to Vietnam.

Today, we are in the Age of Scrutiny. A public figure must withstand the scrutiny of the media. The President is the ultimate public figure and must stand up under ultimate scrutiny; he is like a man stretched out on a rack in the public square in some medieval shithole of a town, undergoing the rigors of the Inquisition. Like the medieval trial by ordeal, the Age of Scrutiny sneers at rational inquiry and debate, and presumes that mere oaths and protestations are deceptions and lies. The only way to discover the real truth is by the rite of the ordeal, which exposes the subject to such inhuman strain that any defect in his character will cause him to crack wide open, like a flawed diamond.
