In an historic moment in U.S. history, the Democratic presidential nominee swept to victory on the strength of key wins in battleground states that were won by President George W. Bush four years ago, to become the nation's first African-American to win the race for the White House.

With the projected number of more than 270 electoral votes, Senator Barack Obama will become the 44th president of the United States. Early wins in Pennsylvania and Ohio almost certainly guaranteed Obama the win but it was Senator John McCain's concession speech at 11:12 p.m. ET that sealed the victory in the eyes of the American people.
"We have come to the end of a long journey," McCain said in a concession speech late Tuesday night. "The American people have spoken, and they have spoken clearly."
Obama is now estimated to take at least 338 electoral votes, a landslide that nears a historic number that few president-elects have enjoyed. Ronald Reagan holds the record for total electoral votes at 525 in 1984. For more information about landslide wins that have exceeded 370, read Analysis favors an Obama landslide over McCain.
