In a first indication of that John Edwards' endorsement of Barack Obama has carried some weight, an Edwards pledged delegate from New Hampshire has now announced his support for Obama, as well.

Edwards' pledged delegates are not required by the rules to follow his support for Obama, though as former activists for their candidate they would no doubt be influenced by his recommendation. Edwards has another 18 delegates up for grabs -- and if they mostly end up going for Obama, it would be enough to wipe out Hillary Clinton's gains from West Virginia.
