It would need to be advertised as a major speech on Iraq (without details leaking too soon) so the networks would cover it.
The facts are there. The media is now, and always will hide them, leaving the vast majority of Americans in the dark about this. The President could go a long way to make this crystal clear.
JMHO.
There's plenty of evidence too. The Able Danger scandal, developing slowly and building over the past several weeks, adds to the increasingly strong case that Al Queda was in tight with Saddam.
There's even evidence that Iraq was involved as far back as the OKC bombing. Why this hasn't been shouted from the rooftops is beyond me.
