dumb girl question: what is tradesports
It is basically a betting website, although it claims it is something else. People are putting their money on Bush.
It's a betting market where you can buy "options" on various events, including the election. If Bush wins a Bush option will pay $100, so the fact that they're selling for $60 means that the market collectively believes Bush has the advantage. In theory markets like this are better predictors than polls because people are backing their beliefs with real money.
