Tom, do you actually think that bellwether counties are some sort of nexus to the nation's political leanings? That we can actually look at how these counties vote and scientifically determine how the entire nation will vote as a result? If the answer is yes, then I think you ought to offer some sort of explanation, because I think most rational people would agree that doesn't make any sense. And if the answer is no, then you should just accept that bellwether counties are fairly interesting phenomena that don't actually mean anything in a scientific or statistical sense. Weird patterns and coincidences form by happenstance all the time, and they stop happening all the time too.
