Below is a direct quote from Palin. If she bowed out because of family obligations and concerns, that's a legitimate reason and I can't fault her for it. But if she said this and then goes on to run for president in a couple of years, how would that square with the family concerns? She's still going to have a family and a disabled child and they're all still going to be put under the microscope if she runs, because that's the sad truth about American politics, every bit of linen in the closet is going to be taken out and aired.
If she goes on to run in the future, this decision is going to come back and bite her, IMO.
"In fact, this decision comes after much consideration, and finally polling the most important people in my life - my children (where the count was unanimous... well, in response to asking: "Want me to make a positive difference and fight for ALL our children's future from OUTSIDE the Governor's office?" It was four "yes's" and one "hell yeah!" The "hell yeah" sealed it - and someday I'll talk about the details of that... I think much of it had to do with the kids seeing their baby brother Trig mocked by some pretty mean-spirited adults recently.) Um, by the way, sure wish folks could ever, ever understand that we ALL could learn so much from someone like Trig - I know he needs me, but I need him even more... what a child can offer to set priorities RIGHT – that time is precious... the world needs more "Trigs", not fewer."
