If Ron Paul owned his name, he would be able to sue anyone else named Ron Paul.
If Ron Paul owned his likeness, he would be able to sue anyone for simply picturing him in their mind.
If Ron Paul owned his "brand", whatever that means, he would be able to sue anyone who imitated his message/delivery/whatever constitutes "brand".
These characteristics of the fellow we call "Ron Paul" are NOT property. They are concepts. Ideas. They cannot be "owned".
