President Barack Obama buried another of his heroes Friday — a role model from his early life and now a role model for the future he’s slowly starting to map out. Shimon Peres, Muhammad Ali, Nelson Mandela: these men whom he's now led the world's goodbyes to were all friends — most don't realize it, but of the three, he actually spent the most time with Peres — part of Obama's pantheon, up there with Lincoln, Gandhi, King.
