This should have been an issue in the 2000 election, but it wasn't, guess there weren't any CIA whistleblowers brave enough back then. Thought just occurred to me, maybe even CIA agents feared for their lives (remembering Vince Foster) with the Clintons still in the WH.
The liberals had damaged Bush's credibility with those questions asked of him concerning world leaders. Possibly, that's why they didn't go there.
Have you seen the original WMD report from the CIA?
