Well I called it right and was also right in saying that the campaign tone would collapse. The Guardian is right in saying that it's important that the Democratic candidates be tested - whether Hillary can appeal to anyone other than her base and whether Obama actually has any big ideas to match up to the rhetoric. But it's also true that if they spend all their energies demolishing each other, it's entirely true that someone like McCain could creep through the middle.
I'm going to call South Carolina for Obama, which I hope is the case because these two can keep proving themselves rather than resorting to desperate measures merely to win. If Hillary wins though, this gets even nastier, the attacks on Bill Clinton will start to become even more frantic, and the nomination gets essentially sewn up. Just too soon maybe to have a just winner.
