If you’re referring to
Citizens United, the idea that the decision was based on some technical concept of corporate personhood is basically a myth. Rather, it was based on combining the right of (individual) freedom of speech with another Constitutional right, freedom of association. To quote Wikipedia:
> The majority ruled that the Freedom of the Press clause of the First Amendment protects associations of individuals in addition to individual speakers, and further that the First Amendment does not allow prohibitions of speech based on the identity of the speaker. Corporations, as associations of individuals, therefore have free speech rights under the First Amendment.
If you’re not referring to Citizens United, well, it’s still a relevant precedent that would prevent your plan from working :)
