The first-term Alaska governor's record on immigration is relatively unknown, The Hill reported Wednesday.

"She's never made any statements. I don't recall really any positions that she's taken," said Mara Kimmel, a political science professor at the University of Alaska at Anchorage who specializes in immigration issues.

Kimmel, whose husband is the Democratic candidate for Alaska's seat in the House, said immigration hasn't been a dominant political issue in the state.

Arturo Vargas, executive director of the National Association of Latino Elected and Appointed Officials Educational Fund, said his group was working to discern Palin's views on immigration.

"I do not know. That's one of the issues we are trying to figure out," he said.

When former U.S. Treasurer Rosario Marin was asked about Palin's position on immigration at a GOP news conference, Marin referred to presumptive Republican presidential nominee John McCain instead.

"I think that one of the things we will see (is) that … we know exactly where John McCain is," Marin said.
