So, it turns out that there are actually two NIE's. The first is the April estimate that was partially released yesterday and covers global trends in terrorism. The second is solely about Iraq and isn't going to be released until after the elections.
Ahhhh, I know this game. Cover up the intelligence community's consensus about Iraq so that the American people can make an electoral decision without being burdened by the facts. Facts are the primary enemy of the Tinkerbell Strategy for Iraq, after all.

Aside: Doesn't it go without saying that when people demand the release of a classified document, they don't mean that the government has to release all of it?

Oh, right... he's dishonest. I always forget that.
