Russ Baker in Slate:
The Bush administration is finally facing tough questions about its selective use of intelligence in selling war with Iraq. But Americans shouldn't just be skeptical of what the president says about WMD. They should be skeptical of what he says about GDP. In economic policy even more than in war policy, the Bushies have successfully suppressed, manipulated, and withheld evidence to serve their policy purposes.
Of course every administration likes to trumpet its good news and hide its bad, but what's remarkable about the Bush team is its willingness to stifle data that had been widely released and to politicize data that used to be nonpartisan.
[T]o heighten the impression that Social Security is running out of money (thereby strengthening the case for allowing workers to divert money from the system into private retirement accounts), the administration has predicted shortfalls far in the future by relying on preposterously long forecast periods.

They lie so much they don't even know when they're lying anymore!
