Bit of a difference here.
Conservatives, for the most part, want The Obamessiah to fail in the sense that his socialist economic policies are repudiated by the American people and he is forced by political pressure to retract or moderate them and compromise with Republicans. We don't want the country itself to fail just to prove a point. We're trying to avoid that.
Moonbats, on the other hand, wanted Bush to fail in Iraq even after we had troops on the ground there, even though that would have meant the death of more U.S. servicemen and -women, innocent civilians, and would have strengthened the sworn enemies of this country.
One forces a change in method to accomplish a commonly desired end, the other calls for the outright death of fellow citzens in order to score political points.
