More on the Meaning of "Maverick"

As Travis writes below, the GOP has bet the farm on the maverick concept. But like most words, it has both positive and negative connotations. Would it be appropriate for a further examination of the word and the idea? 

For while it can be a virtuous word, can it also not suggest risk, recklessness, whimsy, shooting from the hip, unmoored, lack of preperation, self-indulgence, immaturity, impetuousness, not playing well with others? 

Are these traits that will make a successful leader, chief executive or President? In a body of 100, a maverick has its place.  But as the chief? 

Food for thought....
