And especially now when he is on different path in his life, spiritual, healthy living, I can't see any politician doing that.
You just have to make distinction from what people see in him and what is he really inside. So what if he is popular ? So are singers, actors, some scientists, writers... are we going to stamp every popular figure as future politician ? He isn't political Messiah for sure and he knows that. He also knows mud of Serbian politics, and I don't think he wants to wrestle there with other lowlifes. He is tennis figure and will stay in that branch as long as he can.
