Yes, they will. When is she leaving to do that?
I'm not sure. I just have heard, when the plans of the daughters for after college are discussed, that Jenna wants to go to New York, and Barbara wants to go to Africa or one other place, I forget where. I think Barbara wants to be a doctor, so would go to medical school, but I've always gotten the impression that she was going to do humanitarian work before going back to school. The time frame referred to is a vague "after the election".
