Intrade Being Gamed?

I was just looking at the buying and selling of political futures going on over on Intrade and it is very interesting to see where it looks like people are trying to fudge the reporting numbers.

If you look at the most recent trades for Obama in Ohio you see where someone offered 50% less than the current asking price to make the average asking price look lower. In the same you race you can pull up Hillary and see where someone is offering to sell her futures at 4x the current asking price, thus making it look like there has been a spike in pricing.

Since the state races are traded far less vigorously then the national race these types of little games can actually have an effect (as witnessed in the fluctuations in pricing in that particular race today).
