Edwards Is Quitting Presidential Race

    John Edwards is ending his presidential race today. How it affects the Democratic race is anyone's guess -- though it's likely not to have a major impact. The truth is that Edwards didn't have a lot of support left in the Super Tuesday states, except, perhaps, in the south, and even there it was only around 15% or even less. So, while this could help Obama (which is the common assumption), that's hardly a sure thing.
