Whether arrogance has been a primary character trait of men elected to the Presidency is a question. Some have been more arrogant than others, but they've all exhibited arrogance to a degree. Think about those who have held the office. Eisenhower? Truman? Kennedy? Johnson? Nixon? Clinton? Seems to me there was lots of arrogance among that group. About the only ones where arrogance may not have been a primary trait might have been Ford and Carter.

Interestingly, Ford and Carter were both one-term Presidents. Maybe the public likes a bit of arrogance from its President.
