Given the historic vitriol of this presidential campaign, it has been pretty easy to overlook something else historic that makes my heart nearly burst with pride:
It was 53 years ago, six years before Barack Obama was born, that Rosa Parks was ordered to get out of her seat on a bus in Montgomery, Alabama, because of the color of her skin, and today a man of color -- the embodiment of Martin Luther King's dream -- stands on the threshold of the presidency.
This could have not happened in the so-called Party of Lincoln, which has become a lily-white canker on the body politic, but it could happen in America.
Godspeed to you, Mr. Obama.
