If you chose it because it was the leader you didn't do it the right way. The OP made a poll to get the feelings of the users, not in order to guess which one will win the poll. It's not a game.
Personally I voted for VegasPrize because I think playing at Las Vegas is the dream of all gamblers.
Thank you for voting base on what you believe in, and not base on what others are voting. Yes, VegasPrize.com haa been one of my star gambling domains, and it's quite old too.
I'm not surprised about that, it sounds very well IMHO. But it is only in the third position of the results of the poll... it seems people disagree with that, in fact.
