A new U.S. opinion poll is delivering bad news to President Barack Obama, the latest in a series of surveys to show discontent about his handling of the economy.

The Quinnipiac University poll shows a majority of Americans — 58 percent — disapprove of the way the president has addressed the U.S. economy. National unemployment is more than nine percent.

The survey indicates a slide in Mr. Obama's popularity, with 47 percent approving of his job performance, down from 52 percent last month. The president saw a boost in approval in May, following the killing of al-Qaida leader Osama bin Laden in a U.S. commando raid in Pakistan.

Many Americans are expressing frustration with the slow-growing economy as they struggle to find work and pay their bills.

A CNN / Opinion Research poll released Wednesday found the economy was the top issue for Americans.

A recent Washington Post-ABC News poll also found deep disapproval of Mr. Obama's handling of the economy — 59 percent.
