(CNN) - A new national poll indicates that President Barack Obama's approval rating has edged up three points, and it appears that the war in Iraq is behind the bump. But according to the CNN/Opinion Research Corporation survey, Americans are giving the president bad marks on the economy.
The survey, released Friday, indicates that 50 percent of Americans approve of the job Obama's doing as president, up from 47 percent in last month, with 49 percent disapproving, down two points from August. And Obama's approval on how he's handling the conflict in Iraq now stands at 57 percent, an eight point jump from July. The poll was conducted Wednesday and Thursday, after the president gave a prime time address from the Oval Office on Iraq.
"Obama's decision to remove combat troops from Iraq is very popular," says CNN Polling Director Keating Holland. "Only three in ten Americans say that the U.S. should still have combat troops in Iraq, with 28 percent saying that this is the right time to remove them and another four in ten thinking that should have happened before now."
But the poll doesn't suggest that the public's optimistic about Iraq - most say that the remaining U.S. troops will wind up in combat situations and that the Iraqi government won't be able to maintain order once all U.S. troops are removed.
"Only one in five think the war in Iraq is over, and the war itself remains very unpopular," adds Holland.
Six in ten questioned in the poll say the 2007 surge of U.S. combat troops in Iraq was a success. President George W. Bush ordered the increase of troops, but only four out of ten say they approve of how Bush handled the situation in Iraq, with 59 percent they disapprove.
Presidential candidate Obama pledged to bring U.S. troops home from Iraq. Tuesday night President Obama announced the end of the U.S. combat mission in the country. Do Americans think Obama's doing a good job keeping campaign promises? Fifty one percent of those questioned in the poll say yes, with 47 percent saying no.
The poll indicates that the public still give the president poor marks on the economy - with four in ten giving him a thumbs up on the economy and nearly six in ten disapproving of his track record on the issue, which remains upmost in the minds of Americans.
"The fact that Iraq is not the most important issue to most Americans indicates that any advantage Obama gained as a result of his speech on Tuesday will be temporary," says Holland.
Obama's overall approval rating got its biggest bump in two regions where there are a number of endangered Democratic House seats. His approval rating is up six points in the Midwest, to 49 percent. And his 48 percent approval rating in the South is four points higher than in August. More than eight in ten Democrats like Obama and more than eight in ten Republicans dislike him. His rating among independents, at 45 percent, is essentially unchanged since last month.
The poll was conducted as the president led a two day Middle East peace initiative at the White House, which has led to promises of a second round of negotiations later this month between Israeli and Palestinian negotiators. But the survey indicates that only one in four think peace can be achieved in the period ahead - the lowest number of record dating back to 1982, when the question was first asked.
The CNN/Opinon Research Corporation poll was conducted September 1-2, with 1,024 adult Americans questioned by telephone. The survey's overall sampling error is plus or minus three percentage points.
