Your hints: It was

(1) a Democrat

(2) giving a keynote speech

(3) at a party national convention. Go for it!

"I made it because Lyndon Johnson showed America that people who were born poor didn't have to die poor. And I made it because a man with whom I served in the Georgia Senate - a man named Jimmy Carter - brought honesty and decency and integrity to public service."

"I am a Democrat because we are the party of hope. For... dark years the Republicans have dealt in cynicism and skepticism. They've mastered the art of division and diversion, and they have robbed us of our hope."

"Americans have seen plants closed down, jobs shipped overseas and our hopes fade away as our economic position collapses right before our very eyes. And George Bush does not get it!"

"Let's face facts: George Bush just doesn't get it. He doesn't see it; he doesn't feel it, and he's done nothing about it."
