If she doesn’t, then whoever earns her support, and I would assume that would be Perry, then, that would vault that candidate forward big time.I think what she's thinking MIGHT go something like this:
If I run, my high negatives make it very difficult for me -- and with me, all the good people -- to win.
But if I ENDORSE, and endorse intelligently, I can pull off the endorsement coup of the millenium -- and at the same time help all the good Americans I want to help.
Again, just idle speculation on my part, but it is what I'm thinking.
