Bush Supporters Still Believe Iraq Had WMD or Major Program, Supported al Qaeda

Even after the final report of Charles Duelfer to Congress saying that Iraq did not have a significant WMD program, 72% of Bush supporters continue to believe that Iraq had actual WMD (47%) or a major program for developing them (25%). Fifty-six percent assume that most experts believe Iraq had actual WMD and 57% also assume, incorrectly, that Duelfer concluded Iraq had at least a major WMD program. Kerry supporters hold opposite beliefs on all these points.

Similarly, 75% of Bush supporters continue to believe that Iraq was providing substantial support to al Qaeda, and 63% believe that clear evidence of this support has been found. Sixty percent of Bush supporters assume that this is also the conclusion of most experts, and 55% assume, incorrectly, that this was the conclusion of the 9/11 Commission. Here again, large majorities of Kerry supporters have exactly opposite perceptions.
