SC, as for McCain's speech, he came across as a sincere man who would like to serve his country. Did he need to do more than that? I don't know.

In politics, there's a "daddy" and a "mommy" that get elected, one to comfort and aid, the other to be the tough leader. Perhaps on their ticket, it's McCain's rule to be the "mommy". I'm not trying to demean him. It might be a very smart move.
