Why are republicans freaking out so much about tonight's debate moderator?

To me it just seems like they're worried, especially in light of Palin's last "off the cuff" interview, and they're grasping at straws or trying to make excuses in advance for her inevitbale poor performance. Why else would they be worried? Is there's any reason to be?....

A) It's not as if Gwen Ifill was selected to moderate this debate by the democratic party or anything...she was chosen by an independant, bi-partisan panel which has an equal amount of dems & repubs on it, all of whom were searching for journalists with a history of integrity & fairness in reporting...

B) The reason she was selected was because, of all of the people they looked at, she has made a career out of being one of the most objective, fair, un-biased journalists in the country. It's not as if they're going to have Jon Stewart or Bill O'Reilly on either side moderate a debate...

C) The moderator's questions are prepared & scripted in advance and approved before the debate.

D) If it even became remotely evident at any point in tonight's debate that she was trying to favor Biden or help his cause in any way, it would do vastly more damage for Obama/Biden than it would do good...

E) This all seems to stem from a book she is going to have published (AFTER the November elections mind you, so it's not going to hurt or help anyone's campaign anyway), which rebuplicans are trying to say is about Obama, and is pro-Obama...at least one of which is not true. The book is not "about Obama", it's an in-depth analysis at the history of blacks & american politics. Obviously, it's something she knows alot about (she's black & a political journalist), and how could it not included Obama (he's black, and running for president of the US)? Like it or not, he's the first black to run for president, and it most definitley a current world event, so what's the problem with writing a book about that? Furthermore, there's been no indication that the book is "pro" anyone. It's just a book about the history of minorities & the US political landscape.

...I could keep rattling these things off, but lunchbreak is almost over. So anyway, I ask again, why are republicans up in arms over this Ifill woman moderating tonights debate? Is it because they're hedging their bets? Is it because she's black? I don't understand it...it would seem to help Palin more than anything...
