Sure, I remember all those blistering editorials in the Times condemning Clinton corruption, attacking Hillarycare, calling for a Whitewater special counsel, supporting impeachment, attacking the pardon of Puerto Rican terrorists, the sellout to China, the interventions in Haiti and the Balkans undertaken without Congressional authorization. Just like I remember the Times' endorsement of Bush in '92 and Dole in '96. These all occurred in the alternative universe this writer is living in.
Howell Raines is symbolic of the media in general not bringing up facts until late in the game, only after burying the truth didn't work.
I all seriousness, I think what he means is scathing attacks — for not being liberal enough for commie Raines tastes. Signing NAFTA, welfare reform, not inviting Castro to dinner, failing to jail corporate executives (not named Raines), etc.
