CNN Poll: Obama receives a C+

WASHINGTON (CNN) - A new national poll indicates that Americans think Barack Obama's performance as president deserves a grade of C +.

The CNN/Opinion Research Corporation survey, released Thursday as the president approaches 200 days in the White House, asked respondents to use a grading scale of A, B, C, D, and F, where A is excellent and F is very poor.

Twenty-two percent of those questioned gave Obama an A, 32 percent a B, 20 percent a C, 14 percent a D and 14 percent an F. The president's grade averaged out to a C+.

The president received a grade of B minus in a CNN poll taken earlier this year as he approached 100 days in office.

The CNN/Opinion Research Corporation poll was conducted July 31-August 3, with 1,136 adult Americans questioned by telephone. The survey's sampling error is plus or minus 3 percentage points.
