Obama from obscurity to verge of history

And amazing it was. It made it possible for him to stand today on the verge of being the first black person ever nominated for president by a major party.

One could guess the thoughts of the blacks and whites in that crowd: Can you believe that our state -South Carolina, first to secede and first to open fire in the Civil War -is now catapulting a black man to the front of the presidential contest in a year that bodes well for Democrats?

"Race doesn't matter," some began to chant. "Race doesn't matter!"

The cry soon gave way to more familiar chants of "Yes we can," and everyone in the auditorium surely knew that race does still matter in so many ways. But in a pinch-me moment, they seemed to realize that a barrier had been broken with a swiftness and certainty that even they had not foreseen.

Even more astounding, the man vaulting ahead of the universally known former first lady, Sen. Hillary Rodham Clinton, had been a state legislator only four years earlier -a lawyer with no fame, wealth or family connections.

Now, the entire nation and countless foreigners are absorbing a moment that had seemed decades away, if possible at all. Smart strategists and rank-and-file voters ponder how Obama rose so far so fast, and theories abound. Historians will sort it out someday, but Obama's blend of oratory, biography, optimism and cool confidence come to mind most immediately.

It's not just about him, of course. If America can seriously think of putting a black man in the White House, surely it must also profoundly rethink the relevance of race, the power of prejudice, the logic of affirmative action and other societal forces that have evolved slowly through the eras of Jim Crow, desegregation and massive immigration.

Maybe the toughest question is this:

Is Obama, with his incandescent smile and silky oratory, a once-in-a-century phenomenon who will blast open doors only to see them quickly close on less extraordinary blacks?
