Just 21 percent said most congressional members should be returned to office, while 70 percent said they should not, results of the Gallup-USA Today survey released Tuesday indicated.
Voters were more forgiving of their own representatives, with 54 percent saying their current congressional representative deserved re-election.
The poll indicated a pretty even split among voters about whether President Obama deserves re-election, with 47 percent saying he does and 50 percent saying he does not, the Princeton, N.J., polling agency said.
Results also indicated Obama held a 45 percent-to-39 percent lead when voters were asked whether they are more likely to vote for him or for the generic Republican presidential candidate in the 2012 election.
Results are based on nationwide telephone interviews with 1,204 registered voters conducted Thursday through Sunday. The margin of error is 4 percentage points.
