There is nothing to congraulate MMS over. His so-called victory is basically constructed and carried out by Sonia and her stooges. It is not HIS victory, but the victory of the congress and reflection of the ruthless way the congress conducts itself in order to stay in pwoer. MMS just happens to allow himself to be stringed along, very willingly for the sake of enjoying the power - otherwise how else can this mediocre get a chance to enjoy so much power.
If he had taken a personal, moral stand on anything that would go against Sonia and her entourage on the grounds of personal conscience, he would have seen the door long ago. He knows that!
So are you congratulating him on his ability to stay glued to his chair at any cost? If THAT is the reason, I agree he deserves "congratulations."
