He was so vital to the success of the new American nation. Our friends at Power Line call him the indispensable man and they are right.
Washington led an army of colonists and then held together the new constitution by serving as the first president. He could have been "president for life" or reelected to a 3rd term. However, he respected the constitution and set the example by walking away from power.
Washington was indeed the indispensable man to the new nation. Where would we be today without the example of George Washington?
