No, not to protect marriage, to correct an oversight:
[T]he Framers of the Constitution did forget one thing. While we have a Constitutional separation of Church and State, the Framers (not being corporate lawyers) forgot to put in a clause that would separate State and Business.
Without business giving zillions to get whatevers they want passed by government, think what a different world it would be: No campaign influencing checks, no Defense Lobby, no Pharmaceutical lobby, and maybe we’d still have local radio and newspapers, rather than the concentration of powers in the hands of a very few today. Yeah, it’s “efficient” all right. Efficient corporate monoculture.
