“I’m not talking about blind optimism here— the almost willful ignorance that thinks unemployment will go away if we just don’t talk about it, or the health care crisis will just solve itself if we just ignore it. No, I’m talking about something more substantial. It’s the hope of slaves sitting around a fire singing freedom songs; the hope of immigrants setting out for distant shores.... the hope of a skinny kid with a funny name who believes that America has a place for him, too. The audacity of hope.”
— Barack Obama, keynote address, 2004 Democratic National Convention.
