Common ground. That's the challenge of our party tonight -- left wing, right wing.

Progress will not come through boundless liberalism nor static conservatism, but at the critical mass of mutual survival -- not at boundless liberalism nor static conservatism, but at the critical mass of mutual survival. It takes two wings to fly. Whether you're a hawk or a dove, you're just a bird living in the same environment, in the same world.

The Bible teaches that when lions and lambs lie down together, none will be afraid, and there will be peace in the valley. It sounds impossible. Lions eat lambs. Lambs sensibly flee from lions. Yet even lions and lambs find common ground. Why? Because neither lions nor lambs want the forest to catch on fire. Neither lions nor lambs want acid rain to fall. Neither lions nor lambs can survive nuclear war. If lions and lambs can find common ground, surely we can as well -- as civilized people.

The only time that we win is when we come together. In 1960, John Kennedy, the late John Kennedy, beat Richard Nixon by only 112,000 votes -- less than one vote per precinct. He won by the margin of our hope. He brought us together. He reached out. He had the courage to defy his advisors and inquire about Dr. King's jailing in Albany, Georgia. We won by the margin of our hope, inspired by courageous leadership. In 1964, Lyndon Johnson brought both wings together -- the thesis, the antithesis, and the creative synthesis -- and together we won. In 1976, Jimmy Carter unified us again, and we won. When do we not come together, we never win. In 1968, the division and despair in July led to our defeat in November. In 1980, rancor in the spring and the summer led to Reagan in the fall. When we divide, we cannot win. We must find common ground as the basis for survival and development and change and growth.
