That's Congress' latest Gallup approval rating, and yes, it's near an all-time low. It's down 8 percentage points from last month, and only 1 percentage point above the record.
During the last government shutdown, in 1995-96, Gallup polled a few months before the closings and a few months after--it surveyed attitudes on Congress less frequently then. Approval, though, was generally in the 30-35 percent range.
Here's some of Gallup's conclusions this time:
"Members of Congress are no doubt aware that their work as a body receives extremely low marks from the American public -- now within one point of being the lowest approval rating in Gallup history. Members of Congress' concerns about the image of the institution in which they serve, however, may be allayed to some degree by the finding that many more Americans approve of their particular representative than approve of Congress more generally, which has typically been the case.
"Unlike in the past, however, Americans are now about as likely to disapprove as to approve of their own representative. While members of Congress may continue to argue that problems with the image of the body as a whole is not their fault, and that they are doing nothing more than faithfully representing their particular constituents, it is clear that even their own constituents are less positive about the job they are doing than they were in the past."
