an example of a democratic leader at work. If your thinking President John F. Kennedy is a famous democratic leader, you'd be partially correct. You're right in saying President Kennedy was a Democrat and certainly he will be remembered as a great leader. But President Kennedy was actually a very good example of a charismatic leader - not a democratic one.
Interestingly one of the best examples of a democratic leader is also a political figure - Dwight D. Eisenhower (a Republican no less!). As a military leader Eisenhower was faced with the difficult task of getting the Alliance forces to agree on a common strategy. Eisenhower worked hard to make sure everyone worked together to come to a common understanding. This was one of his greatest achievements. It was here that the democratic leadership style and collaborative efforts of Eisenhower shone through and with a victory of the Alliance forces to help back up the correctness of the approach.
