With the federal midterm elections just a few weeks away and party control of both houses of Congress at stake, construction associations, companies and unions are making their late-in-the-game contributions to back favored candidates.

Industry and union spending has been  heavy. Based on reports released as of Sept. 24, construction industry groups and companies have contributed a combined $58.7 million, and building trades unions spent $97.8 million, according to the Center for Responsive Politics (CRP).
