Political funding / Campaigns / Donations

Is there a mod for political financing?
ie. which is important in actually representing how a Democracy works / can be corrupted.

If there is not such a mod, then it is needed.

Suggestion: Maybe having a separate budget for “your political party” which can increase with donations from special interest groups / industry in exchange for favours (policies favouring them), and if the favours are not given the funding is withdrawn in the next election cycle (and if the group is heavily benefited, then they give more in the next cycle).

This funding is then used in a new policy called “political campaign or propaganda” which heavily influences voters (like in reality)

What does the community think?
