(CNN) - The sole Congressional member from Puerto Rico on Thursday hit back against Rick Santorum's call for English to become the official language of the U.S. territory as a requirement for statehood.
"Santorum's view is narrow and a limiting view of what America is all about," Pedro Pierluisi, a Democrat, said on CNN's "Starting Point with Soledad O'Brien" "English is the predominant language in the U.S. and will continue to be so, whether Puerto Rico becomes a state or not."
While campaigning on the island Wednesday, Santorum told a newspaper that in order for Puerto Rico to become "a state of the United States, English must be the principal language." Puerto Rican voters will weigh in on a referendum regarding possible statehood in November.
There is currently no law, however, declaring an official language of the U.S., though several attempts have been made to give English that designation. Thirty-one states have passed laws naming English as their official language.
The Constitution also makes no mention of a language test for territories or properties that wish to become states.
Both English and Spanish are official languages of Puerto Rico, though Spanish is by far the dominant language on the island.
"In Puerto Rico, 90% of our parents want their children to become fluent in English," Pierluisi, the island's resident commissioner, said. "So, it's a non-issue and shouldn't be a factor in determining whether Puerto Rico can join the union or not."
While Republican Gov. Luis Fortuno endorsed Mitt Romney in January, Santorum has been actively courting Puerto Rican voters this week ahead of the island's primary on Sunday. Romney is scheduled to campaign in Puerto Rico starting Friday.
Pierluisi said he expects Romney will win the contest, but the Democratic representative argued President Barack Obama will fare better in the general election.
"(Obama) has told the people of Puerto Rico that he will support the will of the majority of the people of Puerto Rico when the time comes for them to express themselves on the status issue," Pierluisi.
While 20 delegates are at stake in Sunday's primary, Puerto Rico is not allocated any electoral votes in November's election.
