"There’s some indication that Obama actually believes he is the greatest leader since Napoleon. He is “historic”; he is transformational; he is changing the fabric of American society. He’s a lot like Lincoln, Teddy Roosevelt, FDR, JFK, LBJ, and Ronald Reagan combined, only better. And we’re stuck with him for another three years.
For Obama, the Great Man is the man who refuses to negotiate, the one who advances but never retreats, the one who presents himself as “above” partisanship while pursuing his own ends, the “only adult” in the room. That all sounds like another disastrous Great Man: when Lenin’s collectivization of Soviet agriculture resulted in mass famine of 1921-1922, that Great Man refused to admit he was wrong and continued to enforce his mistaken policy. Six million died."
