The New York Times ran a sleazy ad just before Gen. Petraeus testified to Congress, calling him General Betray Us. Cute huh?

Well, it seems the New York Times was feeling extra generous that day:

WASHINGTON - The New York Times dramatically slashed its normal rates for a full-page advertisement for MoveOn.org’s ad questioning the integrity of Gen. David Petraeus, the commander of U.S. forces in Iraq.

Headlined “Cooking the Books for the White House,” the ad which ran in Monday’s Times says Petraeus is “a military man constantly at war with the facts” and concluded - even before he testified before Congress - that “General Petraeus is likely to become General Betray Us.”

According to Abbe Serphos, director of public relations for the Times, “the open rate for an ad of that size and type is $181,692.”

A spokesman for MoveOn.org confirmed to The Post that the liberal activist group had paid only $65,000 for the ad - a reduction of more than $116,000 from the stated rate.

A Post reporter who called the Times advertising department yesterday without identifying himself was quoted a price of $167,000 for a full-page black-and-white ad on a Monday.

Serphos declined to confirm the price and refused to offer any inkling for why the paper would give MoveOn.org such a discounted price.

Citing the shared liberal bent of the group and the Times, one Republican aide on Capitol Hill speculated that it was the “family discount.”

Is there any doubt as to the liberal bias of the New York Times now? Not that there was for many of us before.
