Gallup: 50% of Americans Now Say Bush Deliberately Misled Them on WMDs

NEW YORK Half of all Americans, exactly 50%, now say the Bush administration deliberately misled Americans about whether Iraq had weapons of mass destruction, the Gallup Organization reported this morning.

"This is the highest percentage that Gallup has found on this measure since the question was first asked in late May 2003," the pollsters observed. "At that time, 31% said the administration deliberately misled Americans. This sentiment has gradually increased over time, to 39% in July 2003, 43% in January/February 2004, and 47% in October 2004."

Also, according to the latest poll, more than half of Americans, 54%, disapprove of the way President Bush is handling the situation in Iraq, while 43% approve. In early February, Americans were more evenly divided on the way Bush was handling the situation in Iraq, with 50% approving and 48% disapproving.

Last week Gallup reported that 53% now believe that the U.S. invasion of Iraq was "not worth it." But Frank Newport, editor in chief at Gallup, recalled today that although a majority of the public began to think the Vietnam war was a mistake in the summer of 1968, the United States did not pull out of Vietnam for more than five years, after thousands of more American lives were lost.asdfasdf

No surprise, really. That 50% divide of the country has become quite prevalent. Atrios things it's part of a media bias, which may be the case. I think it's part of a culture of complacency: I imagine (work to be done!) that if we go back and look a those opinions and polls during the buildup, a lot of people had nuanced replys akin to the "Well, if that's what they think then we've got to support our President," "I'm concerned about Iraq having the bombs, but if they're there I'd rather make sure they can't do anything about them, and we should support our President" line of reasoning.
