Polls have been consistent for a couple of years now. They show that while the president's approval numbers are slightly upside-down, they are hugely better than the approval numbers of Congress. It is Congress that the country holds responsible for the mess the country is in.
This survey from the Quinnipiac University Poll (done between August 20th and 25th of a random national sample of 1,563 registered voters, with a 2.5 point margin of error) verifies this once again. But they take it a bit further, by separating the congressional Republican from the congressional Democrats.
The numbers show that the general public is unhappy with both parties in Congress -- but they are significantly more unhappy with Republicans than Democrats. Congressional Democrats have a 15 point lower disapproval rating than congressional Republicans, and a 15 point higher approval rating. Those are significant numbers (well beyond the survey margin of error). Republicans would do well to consider this before trying to shut down the government again (as many of them want to do to defund Planned Parenthood).
The survey also questioned respondents on their approval of the two major political parties -- and the Republicans didn't do much better there. They had an 8 point higher disapproval rating than Democrats, and a 9 point lower approval rating.
