Virtually any inspirational quote that makes you shudder.

From the third Kerry and Bush debate:
In the Oval Office there's a painting by a friend of Laura and mine named -- by Tom Lea.  It's a West Texas painting, a painting of a mountain scene.  And he said this about it -- he said," Sarah and I live on the east side of the mountain.  It's the sunrise side, not the sunset side.  It's the side to see the day that is coming, not to see the day that is gone."  I love the optimism in that painting because that's how I feel about America.
-G. W. Bush
