These kinds of threads mean that anyone involved in any competition, if they don't similarly do what the OP is doing, has no chance of winning.
This isn't a criticism just an observation. Frankly I wish such threads would be banned. They aren't "discussion" threads, and most of the replies are just "done"-type posts.
I had the same thought, but quickly realised it's an idealistic one (even though I agree 50/50). See, even when I was younger, and was in similar voting based competitions that relied on putting tokens in pots etc, I still lost because other kids parents had better connections in the school with other parents etc. So unfortunately, it's life, regardless of whether it's fair or not.
I voted on the basis that OPs daughter has tried hard this year - I'm placing trust in this statement, because if true, I think it's good to reward effort. It can't always be done in every scenario, but I think if I have the opportunity to help out someone who's put effort into something, I'd take it 10/10 times.
