I have some ideas about Germany's political parties. First of all, the SPD was a socdem party, and I recognise they had a large demsoc wing, but I think the SAPD is much more deserving of the title for the demsoc party. One might say, two slots (revsoc and demsoc) for such a small party? And also, the SAPD was Marxist! To which my response would be, the KAPD is more deserving of revsoc and the SAPD is a Centrist Marxist party, meaning they support revolution and reform. Therefore, the commie party is KPD, revsoc is KAPD, demsoc is SAPD, and socdem is SPD.

Also, in the choosing of the chancellor, there is no far-left or SPD options. The KPD and SPD were quite popular at the time. Hindenburg WAS very opposed to them, however, but maybe there could be a possibility to remove him...

I don't know, just speculating here. It's fine if you don't read this, pay no mind to it, or reject it.
