Former Wisconsin Governor Tommy Thompson made his campaign for the White House official and made the claim that he is "the reliable conservative."
"I was a dark horse candidate for governor. I was a dark horse candidate when I ran for the Assembly. I am the underdog, and I don't mind that," Thompson said concerning his chances of winning the Republican nomination.
Thompson's brother, Ed Thompson, has also been mentioned as a possible Libertarian candidate for President in the upcoming election.
