Interesting analogy. Can you imagine the hulabaloo if even *one* district, no matter how small & insignificant, had voted 100% R? The mob would be out in force with torches & pitchforks...
Yes. It would be examined and pronounced impossible by every liberal, academic think-tank statistician (and there are many); then the state media/pundits would carry word of it far and wide (for weeks, months and years on end).
