If the game is balanced then the CIS won't win this poll. From the current results though it looks like it will.
The problem with this game is that the CIS seem to suffer unfairly. Whether that's because they're the weaker side I don't know but I do see a lot of servers where human Republic players vastly outnumber CIS players. That's because of a couple of things...
1. Many players think the CIS are underpowered (true or not it doesn't matter)
2. They're just not cool. Take heed Lucas, robot armies are rubbish!
The game needs a system to encourage balanced teams on player select servers. At the moment, thanks to the crappy player list you can't even tell if the teams are unbalanced.
