Citizens United was that spending money on getting a message out about electoral candidates - "express advocacy" - is protected. That doesn't mean spending money on other topics is protected. Now I can easily see the argument being extended - and it has is some small ways (e.g. FEC vs Cruz) - but Citizens United is pretty controversial even in the legal academy so I don't think it's a given that it would be.
