Dan Forest, the Republican candidate for lieutenant governor, launched a radio ad this week that takes on the state employees association, though not by name.
Forest's opponent, Democrat Linda Coleman, is backed by the State Employees Association of North Carolina, which is running a television ad on her behalf.
"We don't need the unions coming into North Carolina and killing our ability to create new jobs," Forest says.
Forest, a former partner in an architecture firm, says it would be better to have someone with a business background than a former bureaucrat holding the gavel in the Senate. Coleman is a former state agency human resources manager and state personnel director.
