Lyman and Charles Mix counties no doubt have a significant number of white Democrats. Bennett too.
Indeed - there's plenty of white Democrats in the area, if you look at precinct results for towns that are almost entirely white. They're obviously the minority, but they certainly exist in significant numbers.
Yeah, but could one win a primary?
I don't see why not. It's not as if Native Americans aren't used to voting for white Democrats for everything.
After all, Stephanie Herseth's 2006 opponent was an Indian. But then again, he probably was hardly contested.
I think a moderate Indian Democrat is more likely. But how high is NA turnout in the primary?
