Mitt Romney won the Republican Party's presidential primary election in Puerto Rico on Sunday, according to multiple media reports.

Moreover, the magnitude of Romney's victory means he will win each of the 20 delegates at stake, according to CNN.

GOP front-runner Romney won all 20 delegates to the Republican National Convention in August at stake because he attracted more than 50 percent of the vote, concurred The Associated Press.
