Washington : Hillary Clinton won Puerto Ricos Democratic presidential primary by a big margin on Sunday but her rival, Barack Obama, was poised to capture the U.S. Democratic presidential nomination after the final primaries of the contest, in Montana and South Dakota, on Tuesday.
New York Senator Clinton won Puerto Rico by 68 percent to 32 percent for Illinois Senator Obama.
The vote on the island territory was viewed as the last best chance for the former first lady as she tried to argue that she had won more actual primary votes than Obama.
The historic campaign aims to put either the first African-American or the first woman in the White House. Clinton has for weeks resisted pressures to end her campaign and support Obama in the fight to defeat Republican John McCain for the U.S. presidency in November.
Unpledged Democratic “super-delegates” — elected officials and other party leaders — are expected to give Obama enough delegates to claim the nomination as early as Wednesday.
In losing Puerto Rico, Obama gained 17 delegates, leaving him 47 short of the 2,118 needed for the nomination.
The Democratic Party awards delegates based on the percentage of votes candidates receive in each primary.
Clinton has 1,915 delegates, including 38 from Puerto Rico.
