Leadership has become a spectator sport in Arizona. Every flourishing region needs people who act as its stewards. Such leaders see the big picture. They seek visionary solutions that transcend boundaries. They care deeply about the long-term well being of their places. Arizonians have only to admire the advocacy of Mayor Rudolph Giuliani in the days after the New York terrorist attacks to appreciate the powerful role of such leaders, whose passion for their locales leads them to constantly innovate in service of the long-term economic and social success of their regions.
Unfortunately, most Arizonians do not see the state having that kind of leadership today.

Then there is the positive value of separate thoughts imbedded in his strange whimsicality and humor. Lastly, there is the perennial charm of style, which is never a separate quality, but rather the amalgam and issue of all the mental and moral qualities in a man’s possession, and which bears the same relation to these that light bears to the mingled elements that make up the orb of the sun.
