"In contemporary America, power increasingly gravitates to those with an almost obsessive desire to win it. Whoever does not devote himself monomaniacally to the nominating process, whoever is afraid of it or disdains it, will always be pursuing a mirage, however remarkable his other qualifications. With candidates for the highest office, as with athletes, everything depends upon timing, upon an intuitive ability to seize the opportunity."
