The first half of this book seemed quite different from the second half; shorter sentences almost made it seem it was targeting a very young audience.  The information given was common, not exactly riveting.  However, the second half picked up quite substantially.  The writing seemed to evolve from elementary to something more substantive and meaningful.  Comparisons were made but no judgment given.  Illustrations are like caricatures of the people themselves; nicely done.  The end of the book features a list of the presidents, in order, stating the dates served and major events and/or accomplishments during their term(s).
