So said Obama when he was deep in it reports the New Republic:
He told Kellman that he feared community organizing would never allow him “to make major changes in poverty or discrimination.” To do that, he said, “you either had to be an elected official or be influential with elected officials.” In other words, Obama believed that his chosen profession was getting him nowhere, or at least not far enough. Personally, he might end up like his father; politically, he would fail to improve the lot of those he was trying to help.
And so, Obama told Kellman, he had decided to leave community organizing and go to law school. Kellman, who was already thinking of leaving organizing himself, found no reason to argue with him. “Organizing,” Kellman tells me, as we sit in a Chicago restaurant down the street from the Catholic church where he now works as a lay minister, “is always a lost cause.” Obama, circa late 1987, might or might not have put it quite that strongly. But he had clearly developed serious doubts about the career he was pursuing.
Though I would add that the political process is also a lost cause in helping the poor, but that lesson, if Obama wins the presidency, will be one he will learn later.
