On approval ratings

Chapter 39 of Bob Woodward's "State of Denial" begins with a paragraph describing the results of a poll conducted in Iraq the week of November 11 to 18, 2005 that measured the approval rating of various Iraqi leaders. The interesting part of this is in the footnote where Woodward notes that Saddam Hussein had a 22%/78% favorable/unfavorable rating in that poll. After everything he had done to his country, he still had a 22% approval rating. When you consider that the most recent Newsweek poll of George Bush peg him at 28%/64% with 8% undecided, what does this say about Bush and his supporters, not to mention the Iraqis?
