I think this misses what happened.
oh the low population and its whiteness helped it be successful for sure
but Platner is not some kind of organic outgrowth of Maine, he was the cardboard cutout for a massive DC consultant and out of state money campaign
and it could happen in your state
Maine has a population of 1.4M and it's 91% white. One of the oldest and least racially diverse states in the country.
