I don't think that this decision was made lightly. I'm sure she would not be there if she didn't have the support of her family. Their rallying is done. Decisions have been made and soon her daughter will be married with a child. Yes, extended family is important but they don't need to hold your hand.
Even though it is usually the case, who says that a woman has to be the backbone of her family? Many men are stay at home dad's and raise their families quite well.
In case you haven't heard, women today have many rolls. This is one of the direct results of the ERA. Women have fought for the rights that they now enjoy AND that right was spearheaded and heralded by the democrats.
Isn't ironic that now it is those very same democrats that are vilifying Sarah Palin for doing the very thing for which they fought so hard.
Besides all that, where is the outcry when any family man with small children take on such a demanding roll? There is no difference if it is the mother or father when one is still a primary caregiver in the home.
