President Obama's support may be eroding amid reports of surveillance programs and Internal Revenue Service abuses.
A new CNN/ORC International poll gives Obama an approval rating of 45%, a drop of 8 percentage points over the past month.
Possible reasons: Reports of massive National Security Agency surveillance programs that gather phone numbers and Internet activity, the IRS targeting of conservative groups, and actions surrounding the Sept. 11 attack on a U.S. facility in Benghazi, Libya.
"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.
Holland also said: "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."
