If we learn nothing else from this turn of events, it's that this is the kind of election that will have many more turns of events. Polls ask, "If the election was held today, for whom would you vote?" That's all well and good but the election is not being held tomorrow. This time last week, we didn't know who'd be on the bottom half of the Republican ticket. Now, we don't know who'll be on either half of the Democratic ticket and how the world will react to the changes.
I keep remembering the voice of Vin Scully when he'd be covering a baseball game where one team was way ahead and then the other team would suddenly tie the score. Vin would say, "…and it's a brand-new ball game!"
