US electionThe odds narrow

It's far from a shoo-in

LIKE the polls, the odds have narrowed on the Iowa electronic exchange's Presidential market. As you can see from the graph, a steady 60-40 Obama lead has narrowed over the last couple of weeks to 53/47 or 52/48. This is a winner takes all market, so you pay $53 to buy Obama and get $100 if he wins, and nothing if he loses. It has been pretty accurate in the past.
