Whatever one may think about Barack Obama as a candidate or as a potential President, his candidacy has brought something new to the American political scene.

His stunning victory in the Iowa caucuses, in a state where more than 90 percent of the population is white, was an unmistakable signal that racism is not the invincible thing that some seem to think it is.

Unlike Jesse Jackson or Al Sharpton before him, Obama has not been running as a black candidate for symbolic purposes but as a serious contender who happens to be black.

Into this upbeat national scene Bill and Hillary Clinton have brought race back as one of their many sleazy tactics to try to win in any way possible, whether clean or dirty.

First, there were the surrogates bringing up youthful peccadillos that Obama had already admitted in his autobiography. They milked this for all it was worth.

First there was the innuendo, which got media coverage. Then came the claim that the Clintons had nothing to do with the innuendo, which got more media time.

Then came the claim from the surrogate that his statement was misinterpreted, which got still more media time.

But these cheap shots have been by no means as poisonous as Bill Clinton's obvious attempts to reduce Obama to just a black candidate.

Even after much of the media had gotten on him for this, Bill Clinton returned to that theme after Hillary lost the South Carolina primary big time, by saying that Jesse Jackson had won South Carolina before.

It is not that the Clintons are racists. It is just that they will use whatever they want, in order to get whatever they want -- and the effect on the country does not bother them.

That was the hallmark of the first Clinton administration. There is no reason to doubt that this will be the hallmark of the next Clinton administration, if there is one.

If Hillary wins the White House, that will mean 16 consecutive years -- and perhaps 20 -- in which Presidents of the United States have come from just two families.

Surely the country is not that lacking in political leadership. Continued...
