CHICAGO - Barack Obama is promising supporters that "change has come." After his historic election as the nation's first black president, Obama promised to be a president for all Americans - including those who voted against him.
Obama defeated Republican John McCain in one hard-fought battleground state after another, on his way to becoming the nation's first black president. As he did so, his fellow Democrats boosted their majorities in the House and Senate.
It's the first time since 1994 that Democrats will control the White House and both houses of Congress.
Obama 's first speech as president-elect came before a huge crowd in Chicago's Grant Park, where he spoke of the challenges he faces as "the greatest of a lifetime."
In Arizona, McCain told disappointed supporters, "The American people have spoken, and spoken clearly."
Although the popular vote remained close - with the two candidates separated by just three or four percentage points - Obama won a resounding victory in the electoral college, soaring past the 270 votes he'd need and outpacing McCain by better than 2-1.
WASHINGTON - More than a thousand people have flocked to the White House and the surrounding streets to celebrate Barack Obama 's victory. While many stood in the rain in front of the White House chanting " Obama " or "yes we can" others drove around, honking their horns.
In Harlem, thousands of people, black and white, took to the streets, some dancing, others crying tears of joy, in raucous celebration. The roar of a crowd gathered near the legendary Apollo Theater can be heard blocks away.
However, the biggest celebration was in Chicago, where more than 100,000 people filed into Grant Park to meet Obama for his victory speech. There were celebrations from Atlanta to Oakland, California.
