The president's approval rating stands at 45%, down from 53% in mid-May. And 54% say they disapprove of how Obama's handling his job, up nine points from last month. It's the first time in CNN polling since November 2011 that a majority of Americans have had a negative view of the president.
"The drop in Obama's support is fueled by a dramatic 17-point decline over the past month among people under 30, who, along with black Americans, had been the most loyal part of the Obama coalition," says CNN Polling Director Keating Holland.
The president also dropped 10 points among independent voters, from 47% last month to 37% now, with Obama's disapproval among independents jumping 12 points to 61%.
What's behind the drop?
"It is clear that revelations about NSA surveillance programs have damaged Obama's standing with the public, although older controversies like the IRS matter may have begun to take their toll as well," adds Holland.
Views of Obama's personal characteristics have also declined.
The number of Americans who think he is honest has dropped nine points over the past month, to 49%. Fifty-seven percent of those questioned say they disagree with the president's views on the size and power of the federal government, and 53% say he cannot manage the government effectively. Fifty-two percent say the president is a strong and decisive leader. That's still a majority, but it's down six points from last month.
