: The following question is in a recent CBS news poll:
: 'If Saddam Hussein is not captured or killed, then do you think the United States will have won
: the war in Iraq, or not?'

: The 'or not' should have been deleted. Yes?

It's there so that the question will include both possible answers. Without "or not," the framing of the question would bias respondents toward answering yes.
