The Primary That Wouldn't End

I am really excited that Oregon chose Obama. The Tuesday elections went exactly as predicted. And yet, I still feel disappointed. For some reason I thought there would be a resolution. I knew there wasn't going to be, but it's still exhausting. I can't find anyone that can say with certainty when the nominee has to be decided. How much longer can this possibly last? Clearly it has to be over by November, right? I guess the only real answer is "Not soon enough."
