"A More Perfect Union"

This is a brave speach. I think this shows how he can own up to his beliefs and actions. Which is what a great leader needs.
He isn't giving excuses for people he has connections with or people he has supported in his life. The people are challanging him and throwing things at him and his handeling it in a brave and honest manner. He is well connected with todays problems and knows he can't change things but he can start a platform for change, which is the only way that change can be initiated.
