I think these were routinely debunked in real time but there were plenty of people in my Bluer than Blue state who bought the storyline.

On September 21, 2001, Bush was told in the President’s Daily Brief that the intelligence community had no evidence connecting Saddam Hussein’s regime to the 9/11 attacks. Furthermore, there was scant credible evidence that Iraq had any significant collaborative ties with al Qaeda. This was no surprise. Al Qaeda is a consortium of intensely religious Islamic fundamentalists, whereas Hussein ran a secular government that repressed religious activity in Iraq.
Undeterred, Bush and his people continued to tout the connection. Although the Defense Intelligence Agency (DIA) determined in February 2002 that “Iraq is unlikely to have provided bin Laden any useful [chemical or biological weapons] knowledge or assistance,” Bush proclaimed one year later, “Iraq has also provided al-Qaeda with chemical and biological weapons training.” And although the CIA concluded in a classified January 2003 report that Hussein “viewed Islamic extremists operating inside Iraq as a threat,” Cheney claimed the next day that the Iraqi government “aids and protects terrorists, including members of al-Qaeda.”
