A USA Today/CNN/Gallup poll in mid-November found that 37 percent of Americans approved of Mr. Bush, the lowest approval rating the poll had recorded in his presidency. That was down from 55 percent a year ago and from a high of 90 percent shortly after Sept. 11, 2001.
An Associated Press/Ipsos poll earlier in the month found the same 37 percent approval rating and recorded the president's lowest levels regarding integrity and honesty: 42 percent of Americans found him honest, compared with 53 percent at the beginning of this year.
Several of those interviewed said that in the last year they had come to believe that Mr. Bush had not been fully honest about the intelligence that led to the war, which he said showed solid evidence that Iraq had weapons of mass destruction.
"I think people put their faith in Bush, hoping he would do the right thing," said Stacey Rosen, 38, a stay-at-home mother in Boca Raton, Fla., who said she voted for Mr. Bush but was "totally disappointed" in him now. "Everybody cannot believe that there hasn't been one shred of evidence of W.M.D. I think it goes to show how they tell us what they want to tell us."
Mark Briggs, who works for Nationwide Insurance here, said he did not want to believe that the president "manipulated" intelligence leading the country into war, but believed that, at least, Mr. Bush had misread it.
Still, however much he may disagree with Mr. Bush's policies, Mr. Briggs said, he admires the president for standing by what he says.
"There is the notion of leadership and sticking with the plan, which I believe in," he said. "George Bush is clear and consistent. He made a tough decision to go to war - and others voted for it, too. And I think he's right: those people may be trying to rewrite history."
Kacey Wilson, 32, eating lunch with Ms. Martin, said she, too, had concerns about the death toll from the war, but she felt that Mr. Bush spoke the truth, even if it might not be what the country wanted to hear. "I like his cut-and-dry, take-no-prisoners style," Ms. Wilson said. "I think people are used to more spinning."
Others, though, saw arrogance in that approach.
"We need to not be so stubborn," said Vicky Polka, 58, a retired school principal in Statesboro, Ga., who voted for Mr. Bush and described her support for him as "waning." "Something's not going right here. We need to resolve this. I hate to say it, but I think Iraq is going the way of Vietnam."
