Because, clearly, that epithet is reserved for only one man on the world scene. But as Noel Sheppard writes:

I’m not sure what derangement syndrome Bill Moyers is currently suffering from [I'd call it this--Ed], but on Friday’s “Bill Moyers Journal” broadcast on PBS, the outspoken host went into an invective-filled tirade about media tycoon Rupert Murdoch that frankly was one of the most disgraceful exhibitions of liberal bias so far this year.

In his closing monologue, Moyers compared Murdoch to the Marquis de Sade, Imelda Marcos, and Satan himself.

I kid you not.

Speaking of which, apparently AP stands for Ad-Hominem Press these days.
