http://newsbusters.org/blogs/p-j-gladnick/2008/09/13/abc-news-edited-out-key-parts-sarah-palin-interview I can't say I am surprised that ABC would edit out key parts of the Palin interview, sometimes showing her answer to a different question than the one that seemed to be asked, and sometimes removing a huge amount of context so that she looked worse.
I can say I am disappointed once again in the media, however.
The only thing that can be done to address bias like this is to trust that the market place or ideas and dollars and viewers will take care of it, eventually.
