WASHINGTON (CNN) - A new national poll indicates that Americans think Joe Biden's performance as vice president deserves 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 Biden an A, 29 percent a B, 25 percent a C, 13 percent a D and 15 percent an F. The vice president's grade averaged out to a C.
Biden received 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.
