Mitt Romney has sailed to a win in Puerto Rico's GOP presidential primary over chief rival Rick Santorum.
That's according to Enrique Melendez, the Republican representative on the Puerto Rican State Electoral Commission.
He tells The Associated Press that Romney will top 50 percent and win all 20 of the island's delegates to the Republican presidential nominating convention in August.
Next up is Illinois on Tuesday. Polls show Romney and Santorum locked in a close race there.
