I found it hilarious that the best way to "win" is to follow the policies of the NSDAP. Playing the game according to SPD policy would be tolerance/lack-of-action in every turn, and austerity for the sake of toleration.
The NSDAP policy of Braun the President-Chancellor-Minister of Prussia. Massive public spending to boost the economy. Funding and expanding the police and military for aid against enemy paramilitary. And sacking any and all disloyal officers, judges, policeman, etc, in every corner, are as Hitlerism as you can get.
Sometimes the only way to ensure not failing is literally bribing the coalition parties to maintain the coalition.
SPD wins by becoming a non-anti-Semitic NSDAP. Hilarious.
