"And all of this depends on our participation; on each of us accepting the responsibility of citizenship, regardless of which way the pendulum of power swings.   Our Constitution is a remarkable, beautiful gift.  But it’s really just a piece of parchment.  It has no power on its own. We, the people, give it power – with our participation, and the choices we make.  Whether or not we stand up for our freedoms.  Whether or not we respect and enforce the rule of law."

"It falls to each of us to be those anxious, jealous guardians of our democracy; to embrace the joyous task we’ve been given to continually try to improve this great nation of ours.  Because for all our outward differences, we all share the same proud title:  Citizen. Ultimately, that’s what our democracy demands.  It needs you.  Not just when there’s an election, not just when your own narrow interest is at stake, but over the full span of a lifetime."

"I am asking you to believe.  Not in my ability to bring about change – but in yours."

"Yes we can"
