What about this for a twist: The tribe is show the tape of the voting ,so they see who voted for who.
That could work well, actually. But most of the time it is pretty obvious who voted for who, but sometimes this could change the game significantly. Not a bad idea at all!
No actually racer, they do not know who voted for who. It is a bad idea. It makes Survivor pointless.
Well on some seasons (like South Pacific) it was pretty obvious who voted for who at all of the votes except for Elyse, Keith and perhaps Rick.
However, after watching most of Micronesia, I have to agree that in that season, they wouldn't have known at all. I guess I only thought that they would know who voted for who as I have only seen the recent seasons.
