IEM shows shift to 'rest of the field'

There's some interesting wagering in the presidential contest, based on an Electronic Trading Market being conducted by the UNIVERSITY OF IOWA. The graphs show Rudy Giuliani as the odds-on favorite, leading Mitt Romney. But in recent weeks there has been a surge in betting on the "Rest of Field" pick, coinciding with former Arkansas Gov. Mike Huckabee's rise in the polls. On the Democratic side, a vast majority of money remains on Hillary Clinton. But after stagnating over the summer, Barack Obama has started to regain some betting interest.
