GH,

You left out the part that I found most interesting:

"According to the report, this reality gap is something new in American life. "So why do Bush supporters show such a resistance to accepting dissonant information?" it asks. "While it is normal for people to show some resistance, the magnitude of the denial goes beyond the ordinary. Bush supporters have succeeded in suppressing awareness of the findings of a whole series of high-profile reports about prewar Iraq that have been blazoned across the headlines of newspapers and prompted extensive, high-profile and agonizing reflection.The analysis says that the roots of this denial could lie in the trauma of 9/11 and people's desire to hold on to their image of Bush as a "capable protector." It offers no guidance, though, on how ordinary Republicans might be coaxed back to reality.

And while "The Separate Realities of Bush and Kerry Supporters" may be perversely satisfying to Democrats in its confirmation of blue-state prejudices, it carries a pretty disturbing question for all rational Americans: How can arguments based on fact prevail in a nation where so many people know so little?
