Maybe not that much about politicsTo my understanding, these are the key factors before politics really plays a part:
1. Which club is willing to organize such a tournament? Usually clubs wish their own teams to have chances to get a place - this is indeed how the ranked + unranked system was invented, for it created more uncertainty and thus more chances for everyone. Strongest clubs might be interested, but this is obviously not their 1st choice of tournament type - This might not mean the club not supporting chess, but rather how best they can get the sponsors interested.
2. Who has the energy to organize such an event? In fact a club needs someone who's experienced and quite free to organize big events. I've seen some such persons stepping out of the chess circle, Right now maybe the 2 clubs with best chance to do so are White Sands and Bishan. Hopefully later we can see more.
3. Where's the sponsorship? This one I don't need to elaborate.
4. What is the venue? That should be a place easy to reach, be (more...)
well..
you could put it this way, it still falls between the two. With more money, people would be willing to organise more competitions when they get paid more and also search for places to organise them and the ones with the money has the say it's tht simple :P
