I know. I'm only warning those caucus areas may be extremely low turnout or, where that's plausible, have a way disproportionate share of white voters. I'm not saying I think Sanders probably lost Native voters -- that can't be inferred from the data. I'm just saying be careful with the confidence of the inference.
On the other hand, it's pretty damn obvious that Sanders must have done at least decently with non-whites in Hawai'i.
I think in order to average around 80% in the bush districts, he must have won Natives big.
Let's remember caucuses (aside of Iowa) are more likely to produce lopslided results than primaries. I wouldn't be surprised if NH ends up as Sanders' second best primary state after all.
Although, given that NH, thanks to it's voting early, is rarely lopsided, Sanders' win there was still impressive.
Obviously for Bernie to have a shot at the nomination, NH needs to demoted from 2nd place among primary states.
