Considering the enthusiasm Sarah Palin has engendered for the McCain campaign, I think that keeping Palin from doing interviews is an intentional move to keep her name at the center of the storm. Right now the story about Palin is that it's hard to get a story about Palin. She remains front and center. Eventually, the McCain camp will release her for interviews and THAT will be its own distracting media bonanza. Then we will suffer a week more of analysis about "The First Palin Interview." Then she will grant another one and that will become another story. Then we will be in October and it will be time for the debates. The GOP will have controlled September. Sarah Palin isn't withheld because she can't handle a softball interview with Chris Wallace. Glenn Greenwald picks apart that silly notion here.
Palin has proven herself adept at hitting divisive, withering political notes and I'm sure she'll keep at it when she finally does face the easily cowed mainstream media. No, right now she's not granting interviews in order to distract us from the fact that this race is still between McCain and Obama and to deny Obama these few precious weeks to regain his footing, enter the debates on that steady foot, and then begin the fight anew against his opponent.
