How racism works (campaign edition)

Someone I don't know named Kelvin LaFond has written a letter to the editor of the Fort Worth Star-Telegram that describes how racism works in the Presidential election with admirable brevity. I don't know whether that newspaper will/did print it, but I can reproduce it here [minor edits for clarity].

What if John McCain were a former president of the Harvard Law Review?
What if Barack Obama finished fifth from the bottom of his graduating class?

What if McCain were still married to the first woman he said "I do" to?
What if Obama were the candidate who left his first wife after she no longer measured up to his standards?

What if Michelle Obama were a wife who not only became addicted to pain killers, but acquired them illegally through her charitable organization?
What if Cindy McCain graduated from Harvard?

What if Obama were a member of the "Keating 5"?
What if McCain was a charismatic, eloquent speaker?

If these questions reflected reality, do you really believe the election numbers would be as close as they are?

This is what racism does.

It covers up, rationalizes and minimizes positive qualities in one candidate and emphasizes negative qualities in another when there is a color difference.
