Suggestions about mechanics:
1. To make fundraising as an inevitable event in the spirit of the death of a party leader or a crisis. Otherwise, firstly, the problem of safescam, and secondly, the imbalance in the passages due to its different fallout. And so do it once or twice a year as an event.
2. To make snap elections possible if Otto Wels is Chancellor
3. To give special opportunities to politicians who die in the middle of the game. Müller's ability to defend tolerance is de facto useless at this stage of the game. You already have Hilferding with same ability at the beginning. For example, we can recall Müller's work on organizing the media of the Social Democrats under the German Empire. And accordingly, give him ability to cause an event in the media. Secondly, there are too few advantages to Müller's appointment as chancellor. And when the possibility of elections not in 1929 becomes more or less relevant, he dies. In the event of a "hunger chancellor" under Müller, popularity falls rapidly. In other words, there is almost no reason to appoint Müller as chancellor.I propose to remove the possibility of snap elections from him and give different one. Müller was head of the Foreign Ministry in 1919-1920 and signed the Treaty of Versaille. So you can give him an ability to an event at the Foreign Office if he is the Chancellor, even if you don't control the Foreign Ministry.
