Corporations

"There can be no effective control of corporations while their political activity remains. To put an end to it will be neither a short nor an easy task, but it can be done...Corporate expenditures for political purposes, and especially such expenditures by public-service corporations, have supplied one of the principal sources of corruption in our political affairs."
--Teddy Roosevelt, 1910, a couple of years before he broke from the Republican party to form the Bull-Moose party.
