The 10,000-member New Hampshire Service Employees International Union is endorsing former North Carolina Senator John Edwards in the Democratic presidential primary.
The campaign plans to announce the support during a news conference today in Concord, New Hampshire.
Union chapters in Iowa and ten other states have already endorsed Edwards. Two others have endorsed Illinois Senator Barack Obama. The national union has decided not to make an endorsement
during the election, leaving it to each chapter. New York Senator Hillary Clinton has the most national union endorsements with six, while Edwards has four. Senator Chris Dodd of Connecticut has been endorsed by the International Brotherhood of Firefighters, and Obama has an endorsement from a New York City correction officers union.
