It’s two on two and one swing vote... I doubt that type of strategy would be useful in this situation. Out of anyone River stands the greatest chance of winning... In this situation John stands a good chance at winning as the swing as the opposing sides will try and suppress the others ratings.I hope you are right.
Only thing that concerns me is a few of these people will vote strategically in that they will put the one they don't think will win as their number one. I think that played a bit of a factor in Joey winning last year.
