Obama is very dangerous, in my opinion, because he truly believes he is on a mission to ‘liberate’ the world from ‘traditional’ America, and feels entirely justified in breaking any rules he can get away with breaking, as long as it allows him to ‘transform’ America. Don't know if it was him, but he put into place an extensive network of like-thinkers who were willing to bend or break the rules to achieve their goals.
I believe that all candidates for major federal office, including and particularly the presidency, should have to answer publicly the following questions: “In your view, what would an optimal America look like, and what changes do you think are essential? What policies or laws do you think need to be enacted in order to bring about the ‘best’ America?” If you want to ‘change or transform’ America, why and how?
Yes, they could lie, but at least it would have them on record.
If it was Obama they will probably refuse to answer based on executive privilege.
