Edwards plans to appear with Obama in Grand Rapids, Mich., as Obama campaigns in a critical general election battleground state.
The endorsement comes the day after Clinton defeated Obama by more than 2-to-1 in West Virginia. The loss highlighted Obama’s work to win over the “Hillary Democrats” — white, working-class voters who also supported Edwards in large numbers before he exited the race.
Edwards, a former North Carolina senator and the 2004 vice presidential nominee, dropped out of the race in late January.
Both Obama and Clinton immediately asked Edwards for his endorsement, but he stayed mum for more than four months. Insiders believe that Edwards has chosen now to endorse Obama in an effort to re-unify the party. Obama also signed on to Edwards’ anti-poverty initiative, which he launched Tuesday with the goal of reducing poverty in the United States by half within 10 years.
While his endorsement may unify the democratic party behind Obama, it might splinter the Edwards family. Elizabeth Edwards has said she thinks Clinton has the superior health care plan, and did not travel with him to Michigan and is not part of the endorsement.
