Voters are more convinced than ever that most congressmen are crooks.

A new Rasmussen Reports national telephone survey finds that 46% of Likely U.S. Voters now view most members of Congress as corrupt. That’s up seven points from June and the highest finding yet recorded. Just 29% think most members are not corrupt, and another 25% are not sure. (To see survey question wording, click here.)

Similarly, a whopping 85% of voters think most members of Congress are more interested in helping their own careers than in helping other people. That’s a record high for surveys stretching back to early November 2006. Only seven percent (7%) believe most of the legislators are more interested in helping others.

These findings come at a time when voter approval of the job Congress is doing has fallen to a new low. Just six percent (6%) of voters now rate Congress' performance as good or excellent. Sixty-one percent (61%) think the national legislators are doing a poor job.

Rasmussen Reports has asked these questions monthly since June 2008 and sporadically before that.

While some believe that people hate Congress in general but love their own representative, just 31% believe their own representative is the best person for the job. Most think it’s at least somewhat likely that their own representative trades votes for cash.
