Don't these use "virtual" currency?
I highly doubt we can get as much accuracy
out of fake money...the incentives just aren't there.

If markets look ahead, then they would seem to be saying that the Obama panic is on.

There has been a lot of research into the accuracy of virtual money prediction markets. The bottom line is that they can be just as accurate as real money ones. Google for "Does money matter: prediction markets" to find some good research.
