It's stupid to change the election rules just because the icon that is winning is not popular with the some people. Just accept whatever icon wins. It isn't a hard concept here.
It's also not a hard concept to understand why so many people have a problem with the current leader - the CIV style icon.
Whoever it is that designed the icon probably didn't have the civ4 icon in view because if they'd had they'd have realised how much alike the two icons are. Given there's likely to be a good portion of new members with the new civ5 forum, it would not be surprising if many of them voting for that icon simply didn't realise how much like the civ4 icon it is.
It's fair to say it's not something that should be heavily complained about but you have to admit the reasons people have a problem with it are very simple and obvious.
Sounds like sour grapes to me. If they overturn the election can I whine and complain and get a re-election too? We could do this indefinitely.
Of course you can. But keep in mind, it's not about "overturning" the election result, as if this is some democratic government and people are trying to cause a coup. It is about refining the election result because the likely result from this poll is an icon that had barely over 20% approval.
And by the way, this couldn't possibly continue indefinitely. With a finite number of candidates, and even if you took the most drawn out method possible, you'd only have n-1 polls at most. If you halved the number of candidates each time, which is probably still too drawn out, you'd only get roughly log2(n) polls.
*************
My recommendation would be to trim the results of this poll to 4 candidates and if the result of that poll is not more than 40% in favour of any one icon, then go to 2 candidates for the final.
Any voting scheme where there is a large number of candidates and no distribution of preferences and the winner can have significantly less than 50% vote is a bad voting scheme. This is because similarity between candidates actually hurts their chances to win.
Consider for example a country with four states where there is an election for a single leader to govern all four states. Suppose there are five candidates. Four of them have policies that are widely considered fair to all the states, though differing in details. The remaining candidate is very unfair in the sense he proposes to divide up funding between states so that one of the states gets 90% of the total and the other three states get shafted. That particular candidate is going to be very very popular in one of the states. If we assume each state has the same population, then with nearly 25% of the vote there's a good chance that candidate will win the election and govern the four states. This example is a very simple illustration of why it is a bad voting scheme when a candidate can win with significantly less than 50% of the total vote and there are no distribution of preferences.
The weird thing about this poll is that as best I can tell, neither of the two leading candidates would be the winner if this poll was done step by step. This is because many people dislike the CIV icon yet many of the people who like that icon probably dislike the civ5 icon because it's boring. IMHO it would be one of the "V" icons that would actually eventually get the majority vote.
