Here is Mark Hamill discussing which various Star Wars characters most resemble which various American political figures. He discounts any resemblance between Darth Vader and Dick Cheney, see previous post How Cheney Can't be Darth Vader. Hamill then suggests that Indonesian citizen Barry Soetoro most resembles Obi-wan Kenobi.
"Ben" Kenobi was a man in the figurative and actual wilderness. Obama on the other hand has not had a political career long enough to include time in wilderness, unlike Nixon and Churchill. Thinking back on those two, Winnie and Dick, history has proven that Communism and Nazism are both very bad ideas and those that appease or collaborate with the proponents of such political systems are traitors. Obama will probably be looked in disgust for his appeasement of jihad.
