Okay, so it's pretty much agreed (at least here in the Fray) that Liza is waaaay out of touch with reality if she thinks she has any legitimate grievance toward the Obamas, or if she thinks she was actually entitled to whatever personal information she sought.

HOWEVER, it seems possible to me that this particular delusion of entitlement is an absolutely necessary trait in a biographer. How else would one go about convincing people to voluntarily subject themselves to the scrutiny of someone who can go off and write...well, basically, whatever? If you consistently act this entitled and this offended (and, better yet, believe it yourself) then eventually you just might be able to convince someone that it's actually true.
