I don't think someone would change their vote to vote for something else just because of the current standings. If theirs was winning, why would they change? If theirs was losing, would they change to something else that has a higher vote because they really don't want the current one that's winning to win? Also, you don't see who votes who -- but if a vote showed up two seconds after the upload, it would be obvious who did it.

I did that so I could see the results later when the polls end. If you believe I should update it without it then update it with it, I can do that. And why would people be bias after they see the results?
