I think your analogy is wrong for at least two reasons.
1. Butler refused to go along with a coup against Roosevelt. So as much as many here see Roosevelt as a socialist, it might be said that Butler saved socialism in America. The coup plotters could have predicted that Butler was not their man by his writings, speech in support of the Bonus Army, etc.
2. Obama obviously models himself on Roosevelt. If he is FDR, then those muttering about removing him from office early (Freepers among them) are more analogous to the coup plotters rather than Butler.
The Marine in each case was for lack of a better term the pivot on which our history will turn, so my analogy still stands.
Obama is to FDR what Castro was to JFK. Dialectic opposites
