No press releases on the Indiana Democratic primary results from AFT or NEA, so we know Sanders won. It hardly matters anymore regarding the final outcome, but this is an extraordinary result, considering the state of the race and the sheer number of unions behind Hillary.
Still, the unions are fortunate this cycle. They won’t waste effort trying to sell Hillary to these Sanders supporters. They’ll simply emphasize the importance of an anti-Trump vote. Most of the union rank-and-file will get the point, and vote for Clinton. They won’t give her a honeymoon, but by then she won’t care.
