From Grandmaster sports handicapper Joe Duffy, also a political expert. While Sarah Palin has not yet (as of 10:10 EST) committed a fatal blunder, she has not been able to come off script. Biden, who has a long series of gaffes, has neither fumbled nor come across as condescending. We expect Obama will get a solid bounce and go higher than a 300-340 favorite on the latest political betting odds

He has jumped at press time to -295 and has a 66.9 percent chance at winning the White House according to Intrade on the political betting odds page.
