Giuliani Books on Leadership

Rudy Giuliani, former mayor of New York, lists his favorite five top biographies of leaders at Opinion Journal. It is sad to say that I haven't read any of these.  I am particularly intrigued, however, by the contemporaneous bio of Lincoln written by his former law partner William Herndon, and by the bio of Churchill he suggests. And this may be enough to get me back into reading mode again.  Ann Althouse thinks the list is pretty plebian, and that Giuliani picked the "leaders" before he picked the books, keeping his political interests in mind.  Maybe so, it is still interesting, even for that reason!
