Electoral alliances

I think adding pre-election electoral alliances into the game would introduce a cool new mechanic, which could lead to some countries having a party system with a lot of different parties but all organized into 2 or 3 blocs against each other (maybe following some irl electoral systems, parties in blocs could a bit of a bonus compared to if they werent in a bloc, but thats not necessary).
You could probably send a request to another party to form an alliance (preferably being able to write why you want to form one). in elections, the parties are shown separately but visually grouped in with each other. any party can leave an alliance at any time. when it comes to voting on legislation and other things, they'd all vote together for the same laws, so coalition members might have to vote within it how they should vote. also if any party wants to introduce legislation they should prob have to consult the other members too.
Alliances should probably have names and logos (any change to any detail has to be voted on).
i think this would be a cool mechanic to add into the game, please consider it
