As for O'Reilly, even he was a little on the soft side. Big deal, one or two mildly non-easy interviews for every 500 softball pre-arranged 'interviews' ( if you can really call them that ) .
One last point, while Oprah was busy fawning all over Obama back in 2008 in interviews on her show shortly before the election, Palin tried to get on the show as well; Oprah could have done her best to destroy Palin publicly, but she refused to give Palin a voice, would not interview her until after the election. She was afraid that Palin might make valid points, and Oprah couldn't have that now, could she, she wouldn't have wanted her audience to be exposed to information that conflicted with her personal bias.
