Washington: Hillary Clinton scored an emphatic victory in the Puerto Rico primary, but even in defeat front runner rival Barack Obama edged closer to clinching the Democratic nomination for the US presidential race.
A 68 per cent to 32 per cent victory on Sunday in the Caribbean island US territory gave her over two thirds of the 55 delegates at stake, but at least 15 won by Obama under the Democratic proportional system brought him just 49 short of the magic number of 2118.
In a victory speech in San Juan, Clinton told cheering supporters she would have more combined votes than her rival when the primaries end on Tuesday night, claimed victories in key swing states and said that no contender will command enough delegates to claim the nomination.
