>> our country was put to some enormous tests in 1968. it was a bend. but it wasn't a break. >> the issues that were thrown open in 1968, who has authority, who deserves authority, what the limits of power are, those are profound questions that continue to matter. >> this will be an open administration. open to new ideas, open to men and women of both parties, open to the critics, as well as those who support us. and i am confident that this task is one that we can undertake, and one in which we'll be successful.
