We have never liked the idea of police or other public employee unions getting involved in political campaigns. Especially when an incumbent officeholder is favored, it smacks of a pretty big thumb being placed on the scales.

It also leads to the perception that, as the saying of the day goes, there must be some quid pro quo for such support.

In Manchester, the unions are gung ho for incumbent Mayor Joyce Craig. This is the most surprising news we have heard since it was reported that Elm Street dead-ends in both directions. Craig herself is a scofflaw. She has ignored the city tax cap and has pushed for liberal spending on public employee benefits.

Craig also showed her cards with the unions by trying to replace the school board’s negotiations team with one more likely to cave to the teachers’ union’s demands.

The police have a tough enough job to do without their unions getting involved with City Hall politics.
