So, le'ts get the facts straight. Newsweek polls were on the question:
"Do you think Saddam Hussein’s regime in Iraq was directly involved in planning, financing, or carrying out the terrorist attacks of September 11th, 2001?"
September 2003 responses: 47% Yes, 37% No, 16% not sure.
January 2004 responses: 49% Yes, 39% No, 12% not sure.
2007 responses: 41% Yes, 50% No, 9% not sure.
So in 2007 50% of US citizens still either believed Saddam played a role (41%) or thought it's possible, maybe yes (9%).
"Saddam was a Bush thing": you perefectly know this made sense only as history, if referred a past political era, that was until the nineties, before Clinton; nothing to do with the time of the polls, and we are not even talking about the same Bush.
