You can get imperium, thats about the closest thing to what you want sadly.
These are all of the variables you can pull from any given faction, not neccessarily everything you can get that encompases a whole factions context though:
I'd say your next best bet would be to find a variable from the factions characters, but again you're limited in terms of politics variables:
Then finally these are the functions you can use to actually do stuff on the campaign, you are once more.. limited.
Admitadly given all this reachable info and the fair amount of things you can do there are interesting things to be achieved through scripting, politics is sadly limited in this regard however.
