Does the Right to Free Speech Extend to Corporations?

Against 

the Supreme Court ruling of Citizens United v. Federal Election Commission, corporations are afforded free speech. For your essay this week, make a case for or against the constitutionality of not allowing a corporation to promote one political candidate over another (for example, through campaign funding, advertising, compelling votes from employees, etc.). As part of the assignment, use your position on constitutional interpretation and show how that school of thought informs your position.

In addition to the arguments on corporations and free speech in the text book, use at least one additional outside source. Your paper needs to be a minimum of 500 words in length and follow APA style guidelines. You may not use Wikipedia as a source.
