No, the Democrats (and the Republicans) in Congress didn't see the same intelligence as the White House. They saw the intelligence which the White House had prepared for them, which included many distortions and absurd suppositions. VP D!ck Cheney (stupid filter) spent a month at CIA headquarters looking over the analysts shoulders as they rewrote the intel book on Iraq to his specifications. Give people bad, misleading, or intentionally biased intel and they make bad decisions.
