I agree 100% with respect to the first amendment. The only problem Karl is that corporate shareholders already have full individual rights. If a corporation wants to make a political statement they should send a letter to their shareholders and ask them to make it on their behalf.
Corporations with political rights devalue individual sovereignty. This is why no one in DC gives a flying fuck about what the individual thinks.... unless they have "corporate" quantities of cash. Gresham's law applied to politics.
