Breitbart Harvard tape of Obama

I'm puzzled that people are so excited with the tape of the Harvard student era Barack Obama speaking on behalf of Derrick Bell, radical racist professor (nice to see he could speak without a teleprompter, though). I'm more concerned about Obama's behavior today. When word got out the tape was going to run at Breitbart.com, it was then edited by another source and sanitized, taking out Obama and Bell hugging. Would it have made a difference in 2008? He sat in the pew at Jeremiah Wright's church for a decade and ignored the hate and racism there, so this doesn't look too outlandish. Other than the massive cover-up the media did in not vetting him, what's new here? And didn't we know already that the media had his back?
