You can read the results here. Lemme also just copy the two main graphs:
When asked if they have a higher opinion of either Congress or a series of unpleasant or disliked things, voters said they had a higher opinion of root canals (32 for Congress and 56 for the dental procedure), NFL replacement refs (29-56), head lice (19-67), the rock band Nickelback (32-39), colonoscopies (31-58), Washington DC political pundits (34-37), carnies (31-39), traffic jams (34-56), cockroaches (43-45), Donald Trump (42-44), France (37-46), Genghis Khan (37-41), used-car salesmen (32-57), and Brussels sprouts (23-69) than Congress.In fairness, if you take into account the survey's margin of error (3.4 percent), then Congress actually is in a statistical tie with cockroaches.
Congress did manage to beat out telemarketers (45-35), John Edwards (45-29), the Kardashians (49-36), lobbyists (48-30), North Korea (61-26), the ebola virus (53-25), Lindsay Lohan (45-41), Fidel Castro (54-32), playground bullies (43-38), meth labs (60-21), communism (57-23), and gonorrhea (53-28).
I suppose that's something.
