What about having bets on approval ratings for the leaders of the BRICS as a topic? (Obviously separate from one another)
Shall Putin's approval rating be over 80% on January 1st, 2016?
We can use the average of well known local trackers, i.e. for Russia it'd be Levada, or a mix of Levada and VSIOM.
Seconded. I'd love to be placing monthly bets on approval ratings for the leaders of UNSC permanent members + Germany at least.
Especially if you brought them online at once, to close monthly (I agree with picking a defined set of polls on which to base the average, btw) I think it'd be a fun SET of markets to be in, not just of standalone interest.
