This author, is also very much, selective in what he writes and is playing games. The fact of the matter is, sadly, that most of the children of the previous presidents had a great deal many problems. Alcoholism, abusive relationships, infidelities, career failures, and I believe even suicides plagued them.
Al Gore's son now, unfortunatley is also very troubled, he would appear to actually fit the mold if Gore was president. This author seriousley slanted things, of which he knows better, to write this.
It should be noted that the study George W. Bush had done on the children of the previous presidents and what became of there fates cost about $200,000 and was quite depressing.
