Immigration issues have moved to the forefront of political debate in recent weeks, thanks largely to Governor Pawlenty. It began last month when Pawlenty released what has become a controversial report on the costs associated with illegal immigration.

Political observers say Pawlenty is tapping into an issue that concerns many Minnesotans, but he could alienate Latino voters in the process. Minnesota Public Radio's Laura McCallum reports.
