I think most of us are concerned about this one!

All unions, including the AFT, have expressed satisfaction with many of the positions taken by Bernie Sanders, Hillary Clinton, and Martin O'Malley, three of the Democratic candidates. But, like the AFT, some unions will probably endorse one candidate or another meaning that the labor movement will not have a united front for the primary elections.

I do not think that any of this means the labor movement is hopelessly divided when it comes to the 2016 presidential elections. The evidence, in fact, is that the opposite is true, at least when it comes to the issues. There has been an unprecedented amount of unity around the AFL-CIO's raising wages agenda, with almost the entire labor movement pushing the major candidates for the same thing.

In many ways the campaigns of the major Democratic candidates reflect the success of this approach by labor and its allies. It is interesting that in both Clinton's and Sander's cases so far, each has avoided attacking the other, vowing to stick to the issues as they see them.
