(CNN) - A new national poll suggests that Americans think the performance of the U.S. Senate deserves a grade of C.
The CNN/Opinion Research Corporation survey, released Wednesday as the Obama administration marks 100 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.
Six percent of those questioned gave the Senate an A, 32 percent a B, 36 percent a C, 15 percent a D and 11 percent a F. The grade averaged out to a C.
The CNN/Opinion Research Corporation poll was conducted April 23-26, with 2,019 adult Americans questioned by telephone. The survey's sampling error is plus or minus two percentage points.
