Frank Callahan, president of the Massachusetts Building Trades Council, sends us this open letter.

I am sure that many of you share my frustration at trying to sift through campaign commercials and talking points to find out where the candidates for president really stand on issues that are important to you. Part of the problem is Mitt Romney’s habit of changing his positions to suit his audience.

One thing he can’t change is his record. I had a front-row seat for Mitt Romney’s term as governor of Massachusetts. His positions and his actions on the issues that have a direct impact on building and construction trades workers were not good for our members.
