The basic idea is that a delegate would receive 'regional issues' in a regional issue box and would answer them for his region.
A region could have three factors (much like civil rights and economy factors for nations) to decide what government category your region would fall in. The factors are based on civil rights, (except now's its nation's rights), economy (except now its called trade), and political freedoms (okay, defence has little to do with it).
The factors would be
Trade, interregional trade relations ( a divided region, one under war, would have terrible trade relations between nations)
National Soverienty , regional conformity, diversity, (prohibting nations from doing something would lower their soverienty)
Defence, intraregional relations (concepts like isolation and iron curtains)
The system could be mostly behind closed doors, there's no need to have a ranking system on our regions' factbooks for good, bad, or whatever, just a simple tag that says your region's political category. Also the effect tags of these regional issues would appear in your regional happenings.
Here's a rough Ideocube of some possible regional categories...

I needed something to do with my regional categories to "justify" all of that hard work (nudge. nudge.) I put into that graph. So here's a fun
NationStates-esque quiz which determines your region's regional category.
(By the way, my region, the Eastern Islands of Dharma is classified as "Moralistic Alliance", just so yeh know!)
