As a famous person, Ron has to deal with the same issues Beyoncé or Mark Zuckerberg or Bill O'Reilly face.
The fact is, as long as there is no direct copyright infringement (for example, the site McDonalds.com was an infringing site and the restaurant chain won the right to that property), Ron is out of luck.
Even web sites like RonPaulIsGreat.com, RonPaulSucks.com or RonEPaul.com are up for grabs. The smart thing is for all known people (and a vast number of people who are not famous or well known), to minimally protect their "brand identity" by buying your name and/or your company's domain name before someone else gets it. The cost is minimal. This is the reasoning also behind the land grab for Facebook names. These things have value.
