Saddam had to go,

Look who said so:

"We have known for many years that Saddam Hussein is seeking and
developing weapons of mass destruction."
- Sen. Ted Kennedy (D, MA), Sept. 27, 2002

"The last UN weapons inspectors left Iraq in October of 1998. We are
confident that Saddam Hussein retains some stockpiles of chemical and biological weapons, and that he has since embarked on a crash course to build up his chemical and biological warfare capabilities. Intelligence reports indicate that he is seeking nuclear weapons..."
- Sen. Robert Byrd (D, WV), Oct. 3, 2002

"I will be voting to give the President of the United States the authority to use force -- if necessary -- to disarm Saddam Hussein because I believe that a deadly arsenal of weapons of mass destruction in his hands is a real and grave threat to our security."
- Sen. John F. Kerry (D, MA), Oct. 9, 2002

"There is unmistakable evidence that Saddam Hussein is working aggressively to develop nuclear weapons and will likely have nuclear weapons within the next five years . We also should remember we have always underestimated the progress Saddam has made in development of weapons of mass destruction."
- Sen. Jay Rockefeller (D, WV), Oct 10, 2002

"He has systematically violated, over the course of the past 11 years,
every significant UN resolution that has demanded that he disarm and
destroy his chemical and biological weapons, and any nuclear capacity. This he has refused to do"
- Henry Waxman (D, CA), Oct. 10, 2002
