Back when I was a youngster attending elementary school in Detroit (Stellwagen, for all you former Detroiters) my third grade teacher was a rather rigid, proper woman named Mrs. Schuman. (It might have been fourth grade. It was quite a while ago!)
At one point during the school year, we studied about Abraham Lincoln and other presidents. This was the first time I remember a teacher telling me anyone who was legally qualified could become president of these United States. Anyone!
