"People are unhappy there hasn't been a lot of change in direction, for example in Iraq," said Rep. Chris Van Hollen, D-Md., chairman of House Democrats' campaign effort.

Rising gasoline prices could also be a factor, lawmakers said.

In another measure of popular discontent, the survey found that 71 percent say the country is on the wrong track — about even with the 73 percent who said so last May, the worst level since the AP-Ipsos poll began in December 2003.

The survey was taken Monday through Wednesday, before Bush offered to seek compromise with congressional Democrats over a war spending bill setting benchmarks for progress in Iraq.

Bush told reporters Thursday that if pollsters had asked his opinion about Iraq last fall, "I'd have said I disapprove of what was going on in Iraq. They could have put me down as part of the disapproval process."

That was before his decision to send nearly 30,000 additional troops to Iraq, which "would more likely cause me to approve of what's going on in Iraq," he added.

Overall approval of Bush was steady from last month but fell to 69 percent among Republicans, about 7 percentage points below where it had been in April. Earlier this week, a group of GOP moderate House members warned Bush that the status quo in Iraq could mean Republican election losses next year.

"If the war doesn't begin to turn around, Republicans will have problems," said Rep. Peter King, R-N.Y., who said he supports Bush's Iraq policy.

White House spokesman Tony Snow declined to comment on the poll.

Congress' approval rating this week was 10 points higher than a year ago, when Republicans were in control.

But after bumping up in April, this month's drop left lawmakers' job approval where it was when the year began. April saw Congress defy Bush and send him a bill financing the war and requiring a troop withdrawal, which he vetoed May 1.

"People wanted change in Washington" on many issues, not just Iraq, said Rep. Rahm Emanuel, D-Ill., a member of the House Democratic leadership. "I'm not surprised about where people are. They're hearing only about Iraq."

Congress' reduced appeal was evident in several categories of people. Only 48 percent of Democrats said they approved of Congress, down from 55 percent last month. That included a 12 percentage point drop among Democratic women, though support from Democratic men remained steady.

Approval by minorities also fell a dozen points to 39 percent, with a similar reduction among people whose family incomes exceed $75,000.
