Every country has an facist, communist and democratic party. Neutral parties cant be elected, but you can start with them like switzerland for example.
You have advisors for each ideology which lets you drift towards the ideology you want or ideologies can also be supported by foreign countries. Changing your ideology can cause an civil war, while an coup supported by an foreign country always will result in an civil war. The rebells army strenght is determined by the amount of equipment they recieved and how many states join them initialy by how popular they were in the country. In both cases you can choose your side if an civil war is triggered.
Each country will also change its name and flag depending on its ideology. The (democratic) United Kingdom for example changes into the facist British Empire, (democratic) Norway changes into (communist) Norwegian People's Republic, etc.
Johan for example tweeted pictures and comments about his japan, italy and norwegian campaign on twitter. One of the first things he did was choosing an communist advisor and eventually became Norwegian People's Republic and eventually invaded sweden with the help of the soviets.
There we go... first minister slot a communist revolutionary..
And now.. while building up the Industry.. We have a coup!
The Norwegian Peoples Republic lack factories and steel.. I think we need to adjust the borders with the Swedes..
