Not that I think she is like most single mom's, but maybe she's like every other single working mom that travels a lot. I don't know any of them personally, but I'm sure there are some. I think Hilary used to travel a lot when her daughter was young. Dare I compare her to Jackie O (ok, I"m ducking out of the way..don't hit me)? She traveled a lot and left her children behind when they were young with nannies. That's one of the perks of being old..I actually remember when things were said when she left her kids. Although I think it was more a safety issure for her.
somehow, I kind of doubt Kate is targeting the Hillary Clinton or Jackie Kennedy working moms
but, I do see your point.
I hope the kids remember all that quality time.
