Because she's benefited from "the system" as an IRS lawyer (she's more of an establishment insider than she lets on), and because, for reasons I can't quite put my finger on (but think of as she's not been telling accurate truth - but I don't think she's a deliberate liar), I speculate that her heart is more with the powers that be than with those who want to upend the powers that be.
Her endorsement would help Gingrich, if she gave it - but I speculate she'll not endorse anybody.
At the same time, I wonder how much of her support, locally (money and talent) comes from party hacks.
For various reasons, mostly that I think she's quite vain, I think she'll do whatever she believes will benefit her the most. She's not made the impression on me that she is a deep principled thinker (I've said that I think she's a bit of an airhead), I would not be surprised if she endorsed Romney. That might be where her money and power base lie.

I couldn't have said it better myself. I have the exact same sense about her, and have had that sense throughout the campaign.
I know that a lot of our folks really love and admire her, but on this point, I've never really known where she stands. Being this late to the Newt 'party' only strengthens that uncertainty for me.
