John Edwards, who has quit the Presidential race, had the largest bloc of union support of any candidate. His supporters included the USW, the CWA, the SEIU, the Carpenters, and UMWA. Edwards' advisors are suggesting he will not back either of his competitors. However, what about his union backers? Where will organized labour’s support go?
Obama has the support of UNITE HERE and Clinton has the support of AFSCME. If the unions that coalesced around Edwards move as a bloc towards one candidate, it could be enough to put either candidate over the top. Stay tuned.
