Ed Thompson is the former mayor of Tomah, Wisconsin, and was the Libertarian candidate for Wisconsin governor in 2002, in which he received 11% of the vote. He is also the brother of Republican presidential candidate Tommy Thompson.
An e-mail sent out by supporters of Thompson's previous campaign said:
Thompson discussed his potential run today on the Dynamic Duo radio show, http://gcnlive.com/. If neither his brother Tommy Thompson nor fellow truth-seeker Ron Paul get the Republican nomination, Thompson said, "somebody will have to do it."
