It should be no surprise that (according to Bodog.com) Hillary Clinton is currently the prohibitive favorite to win the Democratic Presidential nomination.
Hillary Clinton 1/6Hillary is the big favorite but Barack is within striking distance and interestingly (or more accurately - alarmingly) John Edwards' promises of seizing powers Hugo Chavez style are improving his chances.
Barack Obama 12/5
Al Gore 5/1
John Edwards 8/1
Dennis Kucinich 20/1
Joe Biden 30/1
Personally I'm amused that the "serious" Joe Biden is given less chance than "tinfoil hat" Dennis Kucinich. I attribute that more to the relative hotness of Kucinich's wife but also to the relative blandness of Biden in general.
