The best way to quantify something like this is a "wisdom of the crowds" method: basically let everybody vote and then aggregate the results.

For this to work, however, each of the people voting have to come to independent decisions. The crowd can be as dumb as the dumbest person in the crowd if the crowd falls victim to groupthink.

What I'm trying to say is that you shouldn't let anybody tell you how to vote. Just vote for what you want to happen. Make the decision based as much as possible in complete absence of being influenced by anybody else.

If everybody does that, chances are the result will be the right result.
