Just saw this on RCP. Not a person who agrees with many polls, check this one out and read the underlying questions.
Here is the underlying poll results, 13 pages.
If you read the whole poll you will get treated to the bias against Republicans. The question on ObamaCare was not skewed left but all the rest are. The poll asks if the House or Obama are doing a better job (guess). No question if the democrat Senate is. Same for a question on should Boehner go as Speaker but nothing on Reid. So, they cherry pick their way and I will cherry pick my way. The people don't want ObamaCare and the House will stay Republican. Maybe we will gain the Senate and then the people will have the last word.
