Obama rises from political obscurity to verge of history

Or is he the lucky and well-timed beneficiary of racial dynamics that have changed faster than most people realized, a trend that presumably will soon yield more black governors, senators, mayors and council members?

Presidential campaigns have destroyed many bright and capable politicians. But there's ample evidence that Obama is something special, a man who makes difficult tasks look easy, who seems to touch millions of diverse people with a message of hope that somehow doesn't sound Pollyannaish.

Rep. Elijah Cummings, a black Maryland Democrat who endorsed Obama early, says the Illinois senator convinces people of all races that Americans as a society, and as individuals, can achieve higher goals if they try.

"He says we can do better, and his life is the epitome of doing better," says Cummings, noting that Obama was raised by a single mother who sometimes relied on food stamps. "He convinces people that there's a lot of good within them."

And why should they believe such feel-good platitudes? "Because he's real and he has confidence in his own competence," Cummings says.

Without question, Obama is an electrifying speaker. At virtually every key juncture in his trajectory, he has used inspirational oratory to generate excitement, buy time to deal with crises, and force party activists to rethink their assumptions that a black man with an African name cannot seriously vie for the presidency.

A prime-time speech at the Democratic convention in Boston catapulted him to national attention in 2004. When his presidential campaign badly trailed Clinton's high-flying operation, he gave it new life with a timely Iowa speech that outshone her remarks moments earlier on the same stage. And a heavily covered March 18 speech about race relations calmed criticisms about his ties to his former pastor, although Obama had to revisit the matter when the minister restated incendiary remarks about the government.

Obama has a compelling biography, too. The son of a black African father he barely knew, and a white Kansan mother who took him from Hawaii to Indonesia, he was largely raised by his white maternal grandparents. He finished near the top of his Harvard law class, then rejected big firms' salaries to work as a community organizer in Southside Chicago, where he found a church, his wife and a place that felt like home.

But all those attributes don't explain the Obama phenomenon.

Other great orators have fallen short of the presidency, including Daniel Webster and William Jennings Bryan.
