Obama's political associations growing up were pinkos and Reds. He himself was affiliated with the Democratic Socialists of America in his early political years and joined a church teaching "liberation theology" which has Marxist overlapping, so any Christian worth his salt wouldn't consider him a true Christian anyway. The idea that Jesus "favored the poor" is completely unbiblical. The Catholic Church excommunicated such priests, several of which of whom were associated with Marxist guerrilla movements such as the Sandinistas.
Speaking of that, I'd like to see Obama explain his older videos in which he spoke of taking from the suburbs and giving to the ghettos considering he now claims he's for the middle class. Shaking them down in favor of ghetto dwellers isn't exactly "for" anyone but ghetto dwellers. Marxist economics states taking from the haves and giving to the have nots will raise the have nots, where as in capitalism it states that expanding economic opportunity will help the have nots raise themselves.
