Political speech is indispensable to decision-making in a democracy, and this is no less true because the speech comes from a corporation. By taking the right to speak from some and giving it to others, the Government deprives the disadvantaged person or class of the right to use speech to strive to establish worth, standing, and respect for the speaker’s voice. The Government may not by these means deprive the public of the right and privilege to determine for itself what speech and speakers are worthy of consideration. The First Amendment protects speech and speaker, and the ideas that flow from each.
