For the past two months, Barack Obama's chances of getting reelected have generally vacillated between 60% and 70% on Intrade and other gambling markets.
Before the first debate, these odds hit a peak of nearly 80%... and they've been falling ever since.
Today, Obama's odds fell below 60% on Intrade for the first time since August.
As the candidates prepare to begin the third and final debate, Obama's odds stand at 59.7%.
