Also, Citizens United said money is speech and says nothing about person hood. It was a ruling in 1918 that allows corporations to be recognized as a human being => https://en.wikipedia.org/wiki/Dartmouth_College_v._Woodward).
"He read the ganda!"
Also, I must reiterate: Companies are not people. No supreme court decision has so held. And Dartmouth College v Woodward does not so hold. (Dartmouth holds that companies have the same right to contract as people. It doesn't hold that they are people. The logic is that only people have rights, but they don't lose those rights just because they organize their affairs along a corporate form. And to protect the real rights which real people have, it is sometimes necessary to allow corporations to exercise those rights.[1])
Oh, and while we're at it, Citizens United doesn't hold that money is speech. (Citizens United holds that money facilitates speech, not that it is speech, and that any restriction on things which facilitate a protected action is a - potentially unconstitutional - burden on that activity.)
Your understanding of these cases seems...lacking.
[1]: If you want an example: I get a second mortgage and sink all my savings into a start-up. You can't now come and seize my company, nor my company's assets, without depriving a real person (me) of real property. But I have the right to due process, and by necessity that extends to my company's assets. On the other hand, you can restrict my company from voting (as is, in fact, done) without impairing the rights of any real person. I would lose everything if you take my company's assets; I lose nothing if you don't let my company vote. Every single right that the courts have extended to companies follows this logic: That companies need this right protected in order to protect the rights of real people. The New York Times has free speech not because the Times is a person, but because real people with free speech rights wish to exercise those rights via the Times, and restricting the free speech rights of the Times would be an unconstitutional burden on the rights of those people.
