In terms of personality, I'd say that some presidents are definitely more user-friendly than others. How do you even go about measuring such a thing? Nixon certainly liked to use presidential power aggressively. He was still committed to the idea that the job of a president was to preside and was to try to work out deals with Congress on problems of the day. Nixon still understood, at some level, the importance of governing.
