"The Court has recognized that First Amendment protection extends to corporations. [...] The censorship we now confront is vast in its reach. The Government has “muffle[d] the voices that best represent the most significant segments of the economy.” McConnell, supra, at 257–258 (opinion of Scalia, J. ). And “the electorate [has been] deprived of information, knowledge and opinion vital to its function.” CIO , 335 U. S., at 144 (Rutledge, J., concurring in result). By suppressing the speech of manifold corporations, both for-profit and nonprofit, the Government prevents their voices and viewpoints from reaching the public and advising voters on which persons or entities are hostile to their interests. Factions will necessarily form in our Republic, but the remedy of “destroying the liberty” of some factions is “worse than the disease.” The Federalist No. 10, p. 130 (B. Wright ed. 1961) (J. Madison). Factions should be checked by permitting them all to speak, see ibid. , and by entrusting the people to judge what is true and what is false. [...] If the First Amendment has any force, prohibits Congress from fining or jailing citizens, or associations of citizens, for simply engaging in political speech. If the antidistortion rationale were to be accepted, however, it would permit Government to ban political speech simply because the speaker is an association that has taken on the corporate form."
