The race issue has dogged the United States from the very moment of the country's birth and remains, despite being pushed into the background by political correctness, unresolved. Now, the issue of race is playing a role in weakening Obama and strengthening McCain and almost no one wants to talk about it. Indeed, the issue of race in the campaign has become the province of the lunatic fringe -- such as radio personality Rush Limbaugh. Obama's candidacy, he said on air, "goes back to the fact that nobody had the guts to stand up and say no to a black guy." He also referred to Obama as the "little black man child."

Obama's skin color has, to be sure, already been touched upon in the campaign. For the most part, though, references have been veiled and indirect — and occasionally underhanded.

Hillary Clinton broached the subject with particularly elegant perfidy. When she brought up Robert Kennedy and Barack Obama in the same sentence, the subtext was: Well, Bobby Kennedy was murdered, so maybe it'd be a good thing if I stay in the race.

Bill Clinton compared Obama to Jesse Jackson, a man that has made many white voters uncomfortable in the past. And Geraldine Ferraro, who would have become vice president if Walter Mondale hadn't lost the 1984 election to Ronald Reagan, complained about Obama allegedly being treated better by journalists because of his race -- as if it were some priceless advantage to be born black in America and an insurmountable disadvantage to be white.

Obama was better than Hillary: better at speaking, cleverer in the way he ran his campaign. He was the cool new kid on the block. His skin color certainly didn't tip the scales in the Democratic primary battle, but it seemed not to be a disadvantage either.

Now, though, it's McCain against Obama, Republican against Democrat, old against young -- and, more than anything else, white against black. McCain, of course, hasn't broached the race issue directly. But indirectly, the argument goes like this: To be white means to be like John McCain -- patriotic, bedecked with medals and honors, self-sacrificing and a hero. To be black means to be like Barack Obama -- eager for the spotlight, similar to a Hollywood actor, egocentric, flippant and lacking truly American values. White America is -- subtly and adroitly -- being mobilized against black America.
