SAN JUAN, Puerto Rico (AP) - Mitt Romney has scored an overwhelming win in Puerto Rico's Republican presidential primary, trouncing chief rival Rick Santorum even as the two rivals look ahead to more competitive contests this week in Illinois and Louisiana.
The victory in the U.S. territory was so convincing that Romney, the GOP front-runner, won all 20 delegates at stake because he prevailed with more than 50 percent of the vote. That padded his comfortable lead over Santorum in the race to amass the 1,144 delegates needed to clinch the nomination.
Nevertheless, the GOP nomination fight is unlikely to end anytime soon, with Santorum refusing to step aside even though Romney is pulling further ahead in the delegate hunt.
As Sunday began, Santorum claimed he was in contest for the long haul because Romney is a weak front-runner.
