And to all those who have wondered if America’s beacon still burns as bright, tonight we proved once more that the true strength of our nation comes not from the might of our arms or the scale of our wealth, but from the enduring power of our ideals: democracy, liberty, opportunity and unyielding hope.

For that is the true genius of America: that America can change. Our union can be perfected.

— Barack Obama, Nov. 4, 2008
