When Barack Obama won the Democratic Party nomination and the general election campaign began, there were really only two questions: (1) was Barack Obama "ready" to be President, and (2) was white America ready to elect a "black" (i.e. off-white) man.
Obama answered the first question himself through his thoughtful and "Presidential" campaign, which contrasted sharply and decisively with McCain's cheap, nasty, dishonest, and erratic campaign.
But the second question could only be answered by the American people. And the answer is in: white America is ready to elect a black man.
