Dirty Deeds Done Dirty Cheap

That's why the New York Times gave MoveOn.org a hefty discount on its ad smearing General Petraeus.

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."

'Nuff said.
