Reply #20: They based their votes on lies they were told by the Administration - the only 'reliable' source

[ThomWV]

Remember, they were briefed to the minimum required by law, and then the information they were given wasn't true - Weapons of Mass Destruction indeed. So how else could they have voted, given that the White House was the only official source of information and they did not have any credible reason not to believe the President and his Vice President, or their Secretary of Defense. Granted, those were despicable sources, but at that time they they had not proven themselves to be criminally incompetent or worse, that would come later.
