Right. Which means Obama's dismal 29% approval number might be even LOWER if those people DID have an opinion about him. But in the meantime, all you can do is use the poll findings among those who DO have an opinion, and in that instance, CBSNews found that Obama only has a 29% approval rating, versus Bush's 33% approval rating, and Hillary's 36% approval rating. Yet the Driveby Media continues to speak of Bush's "very low" approval rating, and NEVER refers to Obama's "very low" approval rating. Leftist Media Bias anyone?
