We get it, Senator. Barack Obama has claimed solid Kansas values (though he grew up overseas and his fathers were both from overseas). He claims the 1965 March on Selma resulted in his conception in 1961 (not only is he the Messiah but he has the ability to travel back in time), and now he tries to claim descent from a legendary American figure, Wild Bill Hickock, associated with that most American of archetypes- the cowboy.
Worked for Ronald Reagan..and the Marlboro Man, why not for him? Barack Obama made this claim in Missouri, the proverbial "Show Me" state. He has a vast amount of funds at his disposal. Certainly, his genealogy could have been researched before making this claim.
Guess that relation works better than the one with Dick Cheney.
