All of the Democrat contenders present at a recent labor convention in Iowa, of course, pandered to Big Labor. Bernie Sanders touted his plan to double union membership by the end of his first term. However, in contrast to the 2016 primaries, unions in Sanders neighboring state of New Hampshire are not buying it and have abstained from endorsing him. The exception is SEA/SEIU Local 1984, who decided to back Sanders even though SEIU International is still on the sidelines. In contrast, Elizabeth Warren just scored the endorsement of 60 union leaders and members from the granite state.

For Elizabeth Warren, the USMCA trade agreement has her in a bind. Though her vote is unlikely to affect the outcome of the agreement, if she supports it she risks angering key constituents in swing states, and if she opposes it she is going against her party leadership and the AFL-CIO.
