I do agree that the media likes Obama more than Bush. But, I honestly think that most of that is based on shallowness not partisanship.
I do totally part ways with you on this one Amy. I could list example after example but there are websites that do that quite well. Left leaning bias in the media is sometimes blatant but not always. Sometimes it is a simple as the use of a certain word in a headline that changes the tone of the story from neutral to bias. Journalism in general is truly not an honorable profession anymore imo.
I agree you could find bias. I think more subconscious, people are all naturally biased.
However I think the abject dislike of Bush, compared to the coddling Obama gets, is not really about dem vs pub. It's an image issue. Obama is charming, handsome and well spoken. Bush had a southern accent, was a bit goofy looking and bumbling.
