U.S. Democratic presidential hopeful Barack Obama says he is within reach of the party's nomination after splitting Tuesday's primary elections with rival Hillary Clinton.
After his win Tuesday in the northwestern state of Oregon, Obama needs fewer than 100 delegates of the two-thousand-26 needed to secure the nomination.
Clinton won by a big margin in the east-central state of Kentucky, but it does little to help her overcome Obama's delegate lead.
The New York senator and former first lady has vowed to stay in the race through the final three nominating contests in Puerto Rico, Montana and South Dakota. The last races are being held June third.
At a campaign event in Tampa, in the southeastern state of Florida on Wednesday, Obama tried to relieve concerns that the prolonged race with Clinton is dividing the party. He said Democrats will unite in November to defeat presumptive Republican candidate John McCain in the general election.
