Email (excerpted), response to PolitiFact Texas, Joe Hunter, communications director, Gary Johnson presidential campaign, Sept. 18, 2012
… As of today, Governor Johnson is officially on the ballot in 47 states plus the District of Columbia. The remaining three states, Michigan, Pennsylvania and Oklahoma, are involved in litigation and/or challenges to petitions, with our campaign maintaining that we have qualified for the ballot in each. That is the basis for Governor Johnson's statement and pledge that he will be on the ballot in all 50 states. For a complete list of the states, see: http://www.lp.org/2012-ballot-access
Regarding other "third party" candidates, none are on the ballot in more than 40 states at this time, and historically will have a very difficult challenge gaining ballot access in all 50, or even 47.
