A reader notes that the early exit poll numbers had Romney winning Delaware, by a considerable margin, and it’s being called for McCain, and asks, does this mean all the exits are no good?

Short answer is, I don’t know. I don’t know if the samples were too small, or if the exit pollsters haven’t had to pay attention to Delaware in so long that they take their samples from the right areas. This is why I suggest a certain level of caution and skepticism when I post them.
