Sorry, JohnGalt80... Ron Paul is not trademarked. A name by itself cannot be trademarked, however, Ron Paul, Inc. could be trademarked, or Ron Paul brand t-shirts could be trademarked, or Ron Paul bumper stickers could be trademarked. Even Ron Paul brand chainsaws could be trademarked. RonPaul.com is also a trade name.
As another person put it better than I, "In order to earn trademark rights in your name (or register it as a trademark) you must be using it "in commerce" as an identifier of the source of goods and services."
Frankly, Ron's people have been very sloppy when it comes to managing these things. He still has the value of his career, the value of his books, and great name recognition. I just hope some new idiot isn't making decisions for him that long term reflect badly on his name.
