CNN Poll: Senators receive a C+

WASHINGTON (CNN) - A new national poll indicates that Americans think the performance of their U.S. senators deserve a grade of C+.

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

Eleven percent of those questioned gave their senators an A, 28 percent a B, 32 percent a C, 12 percent a D and 10 percent an F. The grade averaged out to a C+.

Americans also gave their U.S. senators a grade of C+ in a CNN poll taken as the Obama administration 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.
