Romney's Massachusetts... ...Suffered the second-largest labor force decline in the nation: Only Louisiana, which was ravaged by Hurricane Katrina in 2005, saw a bigger decline in its labor force than Massachusetts during Romneys tenure as governor. The US Census Bureau estimated that between July 2002 and July 2006, 222,000 more residents left Massachusetts for other states than came to it. That decline largely explains the states decreasing unemployment rate (from 5.6 to 4.7 percent) while Romney was in office, according to Northeastern University economics professor Andrew Sum. At the same time, the nation as a whole added 8 million people to the labor force.
