Confusing 2016 trends that may continue:
Lake County, CA
I wish I had a good answer. Trends were towards Trump all along the remote northern California coastal areas, but not nearly to the extent of Lake, and unlike some of the other counties, Stein didn't do exceptionally well there (3.77% is nothing to sneeze at for a Green, but it's a lot less than 5.56% in Mendocino or 6.13% in Humboldt). I do think the resort/retirement parts of Lake are somewhat less upmarket than in Mendocino and Humboldt (a lake isn't as prestigious as the ocean, I suppose), and there are more retirees and other assorted relocatees from the Sacramento area in Lake, but that doesn't really explain things, either, since Sacramento also moved hard to Clinton. Lake also has some flatland farming around Kelseyville, but the farm areas in northern California otherwise didn't move sharply towards Trump.
I would expect there to be a significant snap back to the Democrats there on the basis of climate policy in 2020, though. Forest fires have spooked the whole region.
