Update 2: From Crack the Bell:
Just got an email from Daniel Boan (Edwards pledged delegate from SC):
"Sen. Edwards's endorsement will be an important factor in how I decide to vote."
Update 2A: Supposedly John Moylon and Lauren Bilton said on CNN last night they were supporting Obama. We'll try to find confirmation. More from CNN:
He said at least six of his eight delegates in South Carolina are prepared to endorse Obama.
"I think you will see overwhelming support of John Edwards delegates standing with John Edwards, and now standing for Barack Obama," he said on CNN's "American Morning."
Update 3:The co-chair of John Edwards’ presidential campaign in Iowa, Rob Tully, said he hopes the former vice presidential candidate’s supporters in the state heed his endorsement Wednesday of Barack Obama. “I was excited to see him endorse Obama,” Tully said. “I’m certainly going to follow his lead.”
...
Tully said he would reach out to those delegates, as well as others going to the state convention, encouraging them to close ranks behind Obama. “I encourage all our Democrats in Iowa to realize this race is over,” he said. - Quad City Times
