I'm trying to understand the political mechanics in FtM better. Generally, it looks like we have two ways to influence politics via ministers: support ruling party and internal drift. I'm not clear exactly what internal drift does or how it works. Beyond this, I'm wondering what the other factors of the political system are. Via Intelligence, you have support ruling party and counter-espionage. The former has a fairly direct consequence: it will raise the organization of the party in power. This in turn appears to have some effect on party popularity, but not as much as one may think. It appears that internal drift is the primary factor in popularity, but I'm not sure how it factors in. Counter-espionage, in theory, will help on occasion preventing other nations from supporting their ruling party, so I can see how that should be thrown into the mix every once in a while.
My current use-case for politics is Japan. It appears possible by around 1941 to eliminate the fractured government malus, which is frankly a minor point anyway, and get part organization into the 80% range. I suppose this leads to the final question which is: do political parties really have that much impact on gameplay in FTM?
