Qualities of a truly great politician.........

 This, then, is a story of Lincoln’s political genius revealed through his extraordinary array of personal qualities that enabled him to form friendships with men who had previously opposed him; to repair injured feelings that, left untended, might have escalated into permanent hostility; to assume responsibility for the failures of subordinates, to share credit with ease; and to learn from mistakes. He possessed an acute understanding of the sources of power inherent in the presidency, an unparalleled ability to keep his growing coalition intact, a tough-minded appreciation of the need to protect his presidential prerogatives, and a masterful sense of timing. His success in dealing with the strong egos of the men in his cabinet suggests that in the hands of a truly great politician the qualities we generally associate with decency and morality – kindness, sensitivity, compassion, honesty, and empathy – can also be impressive political resources.
