KOGELO - US President Barack Obama’s half brother has hit the campaign trail in his native Kenya in a bid to get a county gubernatorial seat in the upcoming March 4 elections. Malik Obama, 54, who shares a father with the US president, told AFP that the achievements of his more famous brother have “inspired and challenged” him to get into politics. “When I look at the success that my brother has had in America, I feel I would have let down my people if I do not follow in his footsteps,” Obama told AFP in an interview late Wednesday in his ancestral home of Kogelo in western Kenya.
