U.S. governors eyeing a growing U.S. economy are proposing incentives to draw skilled workers to their states. New Mexico Gov. Susana Martinez says 32 of 33 counties in her state are short of health care workers, and paying off student loans for nurses and other practitioners could be one incentive to attract more qualified applicants. In South Dakota, Gov. Dennis Daugaard is pursuing a plan to provide incentives for preceptors of new nurse practitioners.
