What if the handicapper is a RINO...?
RINO see things in guarded delusion else they wouldnt be RINOs..
There is no "handicapper" at Intrade; the odds are reflective of people's bets, automatically.
Predictive markets (where people put up their own real money) can be remarkably accurate, so much so that they have been examined by the CIA, etc.
The overwhelming majority of people are judging that Romney ends up winning the nomination, despite Santorum being ahead in the polls at the moment.
You can of course go ahead and bet lots of money on Santorum, if you wish, if you think the market is wrong. Real money tends to make people think real long and hard if they are engaging in wishful thinking, however.
Exchanges are head-to-head, with the house taking the vig. Not possible every punter is a RINO.
