Many of the unions that spent the most on lobbying activities are also among the top overall campaign contributors, but there are some exceptions. The Brotherhood of Maintenance of Way Employees, which represents railroad track workers, was among the top spenders on lobbying but did not rank among top campaign contributors. The union is weighing in on proposals affecting Amtrak and railroad safety.
Most unions do give more in campaign contributions than they spend to hire lobbyists.
The United Auto Workers union and the AFL-CIO, however, did the opposite. Total represents amount declared on lobbying report the company filed for itself. For companies that did not file their own lobbying reports, totals represent sum of all amounts disclosed by individual lobbyists.
