Excerpt:Â Who is Barack Obama? The truth is neither Sen. Obama's supporters nor opponents can answer that question. We know he is bright, eloquent and charismatic. But if he were elected , he would be the least-known man to be elected in modern American history, perhaps in all of American history. That is why the remarks and views of those closest to Sen. Obama take on much more significance than the remarks and views of the people closest to Sens. and John McCain. Whether we like or dislike either of those two candidates, we have every reason to believe we know them.
