Depressing Poll

I saw this on the plane yesterday morning and couldn't believe my eyes. I think it is absolutely unacceptable that half of the country still believes this stuff:
More than half of Americans, 54 percent, continue to believe Iraq had weapons of mass destruction or a program to develop them before the United States invaded last year, according to a poll released Friday. Evidence of such weapons has not been found. Half believe Iraq was either closely linked with al-Qaida before the war (35 percent) or was directly involved in the Sept. 11, 2001, terrorist attacks on this country (15 percent). The poll by the Program on International Policy Attitudes at the University of Maryland found the numbers on both questions have dropped in the face of evidence that both pre-war claims may have been false.
Then there is this:
Seven in 10 in the poll say they believe the United States went to war in Iraq based on false assumptions. A similar number say the war in Iraq has given the United States a worse image in the world. A majority, 55 percent, say they don't think the war in Iraq will result in greater peace and stability in the Mideast. In various polls, people have been evenly split on whether the war in Iraq was the right or wrong thing to do - a sharp drop from last winter. The poll of 733 adults was conducted by Knowledge Networks from Aug. 5-11 and has a margin of sampling error of plus or minus 3.5 percentage points.
So half the polling group thinks that Iraq had WMD and legitimate ties to Al Qaeda, but 70% believe the US went to war based on false assumptions???!! That makes my head hurt. There will always be 10% to 20% of the population completely out of touch with the reality of the situation, but there is no way that 50% should still be completely wrong this far after the war! Straight from the horses mouth.
