good link dheiman. I would point out that the 76% is the lowest rating it has had in 19 years. the previous low the link mentions was in August at 70%. So that is dropping and very low. Which backs up my main point that the public opinion of Congress overall is very low right now.
Now yes the poll is a little bit reversed in terms of how the polsters felt about their local representative. However the 53% is still historically low as the link mentions. It may be higher than expected based on the previous # but it is still very low compared to what it has been in the past.
