More sexist views IMHO - a women who's motivated to achieve greatness in her career is automatically assumed to be ignoring the interests of her children. Spin this around, what if her husband were running instead of Sarah? Would we be sitting around discussing how Todd Palin was doing a disservice to his family for running for V.P.? I think not. Is Obama doing a disservice to his daughters by running for President? I think not. So why is Sarah? The only difference here is the fact that she's a woman.
Just want to throw out the obvious fact that the mother's role in raising her kids and relating to them is much different than the father's both physically and emotionally. I just don't see a straight-up comparison.
