Reuters interviews with dozens of activists and union leaders reveal an unusual Sanders union strategy that can be summed up in one word: Stall.
Rather than pressing for endorsements, the pro-Sanders group Labor for Bernie is asking national unions to at least stay neutral for now. They hope this will buy time for Sanders to convince labor he is electable in the November 2016 presidential election.
Sanders' supporters say strong showings in the debates and early primaries will demonstrate his viability and bolster his support. That, in turn, would put him in a stronger position to push for endorsements.
Still, said Sander's Iowa state director, Robert Becker, it will be on-the-ground organizing, not national endorsements, that will be crucial in getting workers to take part in the early Iowa and New Hampshire nominating contests.
