There is no difference between Republican and Democratic party - they both are proxi-parties, the sort of virtual dihotomy, supporting the impression of two hot contradictions. Their real aim is only one - to change one another if the job is going bad and to make you think the wrong guys always are being replaced with good ones with 50,5% against 49,5% as the ideal democracy model should look like - and of course, you think your state is the instance of Ideal Democracy - how else?
It is mathematic. GIVEN - Both parties support the war plans. There comes the logical fork then. IF the war plans were successfull - OK, the "ruling" party stays as leader.

REPEAT UNTIL (Conditions as follows).
