Now let me preface this by saying the exits could still be wonky with groups like this - but
That is actually the correct answer, you could have stopped right there and the post would have been better and answered your own question.
Is the implication that Beasley did better with young voters than exits suggest? I totally get that could be correct answer here, but where's the proof? Why would the exits be more off in NC than elsewhere?
Because exits being off don't mean that they are statistically biased in a direction, but just have high variance?
