that intrade map is WAY OFF as far as Pennsylvania...
This is still a low volume period for Intrade so it can be manipulated for effect for not a lot of money.
Take a look at volume for Obama and Romney today. Last time I looked (an hour or so ago), the Obama volume is twice what the Romney volume is...yet Obama doesn't have twice the enthusiasm in this country or around the world.
Manipulating Intrade is a cheap and easy form of political advertising for Obama.
Watch what happens 48 hours before the election.
