Read this article (emphasis added):
In the 2000 presidential election, 1.9 million Americans cast ballots that no one counted. “Spoiled votes” is the technical term. The pile of ballots left to rot has a distinctly dark hue: About 1 million of them — half of the rejected ballots — were cast by African Americans although black voters make up only 12 percent of the electorate.
This year, it could get worse.
