Gallup:
For the first time, a majority of Americans, 51%, say the Bush administration deliberately misled the public about whether Iraq had weapons of mass destruction -- the central justification given for invading. The administration's credibility on the issue has been steadily eroding since 2003 after stores of the weapons weren't found.
By 58%-37%, a majority say the United States won't be able to establish a stable democratic government in Iraq, similar to the results when the question was asked in April 2004.
About one-third, 32%, say the United States can't win the war in Iraq. Another 21% say the United States could win the war, but they don't think it will. Just 43% predict a victory.
On whether the US should've sent troops to Iraq, 53 percent says "yes", the strongest number since the January elections. Kind of weird, considering the utter lack of progress in the war.
