Five of the top 10 Massachusetts political action committees active in the 2018 elections represented construction unions.  In total, 8 of the top 10 PACs represented organized labor.

While the Service Employees International Union PAC topped the list, construction unions dominated the Top 10 with PACs funded by union laborers, electrical workers (two PACs), pipefitters, and ironworkers. The construction union PACs raised more than $1 million and spent more than $725,000 to elect candidates with position favorable to them, according to data from state campaign finance regulators.

PACs are formed to support or oppose candidates, and are limited to giving $500 per candidate. Union-backed PACs are generally funded by withholdings from union member wages.
