Of course... it's all the fault of Obama and his supporters. Sen. Clinton's supporters are blameless and pure as the fresh-driven snow. If Obama had not actually contested the primary and just let Sen. Clinton win, our party would be so united...
The devision was to be expected. You can't get a group of people who all want the same thing together and give them two choices. I think this a great example of what can happen when you bring passion into politics. If we as voters went along with apathy we are known for, none of this would have happened.
I don't think we can blame Obama or Hilary or their supporters for this. There is a division but its only because people are too set in their opinions of one versus the other. What is wrong is the entire mentality of "well, Hilary didn't win so I am voting for McCain". People just need to get over themselves.
