I think it tells you something if Hillary with her +10 favorability is leading Bush with his -11 one by only 4 points.
Hillary is a really flawed candidate.
Hillary is not really flawed. 
She is just no Obama. Who was by far the greatest presidential candidate of any party since Bobby & John Kennedy.
Was Obama a better candidate than Reagan? I don't think so. Obama fared pretty poorly among working class whites. Compared to other Democrats, Obama overperformed in the big cities and underperformed in the small towns.
Barack Obama is the ultimate urban-suburban candidate, someone at his best wowing big crowds but ineffective otherwise. He wins because Suburbia has become increasingly urban while losing its rural characteristics.
He won because he picked off much of the vote that Republicans used to count on in Suburbia. The suburbs in which he fared worst were the newest ones, those that still had some bucolic qualities (Dallas, Houston, Atlanta).
