WHomever was reporting about it on CNN tonight said the second NIE wasn't even finished, and would not be complete for several months.
In fact, they noted, it was just started in July or August.
I was talking to a liberal friend at work, who admitted to me that the current NIE was probably leaked by his side of the political fence, and wouldn't amount to...as he deemed it..."A cup of warm pee."
Bush doesn't have to release the new NIE, it will just get leaked to the press anyway.
