Long answer (correct answer): Since Obama's stated goal is to "fundamentally transform the United States of America" (to significantly weaken us on the world stage and at home), most, if not all, of what he's doing and has done should very much be considered a success (from his hard-left, anti-American point of view). Now if his goal were to do what is right or best for America, THEN we can evaluate his actions and decisions in terms of successes or failures.
Well, yeah … from that point of view. But from the view of what’s good for this country, he is a miserable failure.
