Do you get the impression he really doesn't care for his family? I haven't seen it.
You have to admit that his trip to Hawaii to his dying grandmother was marked by the omission of taking his children to visit her. And that in the aftermath of his nomination acceptance speech he didn't have his family with him onstage as every other major party nominee in the modern history of political conventions has done. People were asking what was up with that . . .
Cut him some slack. He had birth certificate business to deal with. What was more important for his girls, seeing great grandma or being the children of the president?
