WALTER E. WILLIAMS: “We must ensure that the 2012 elections are the most open and honest elections in U.S. history. Should Obama lose, I wouldn't put it past leftists, progressives, the news media and their race-hustling allies, as well as the president, to fan the fires of hate and dissension by charging that racists somehow stole the election, thereby giving support and excuses for the kind of violence and lawlessness that we've witnessed in flash mobs and Occupy Wall Street riots.”
