Minnesota is among four states hoping to hang on to a seat in Congress after the 2010 census, the state demographer said. Tom Gillaspy said Minnesota would lose a seat in the U.S. House of Representatives if the census were taken today. He said the state is competing with Georgia, South Carolina and North Carolina. Minnesota has had eight House seats since 1960. "The difference is very, very small," he said, "easily within any estimating error and easily within a slight modification in growth rates."
