Single Most shocking county result?

[politicallefty]

I didn't think Orange County was that surprising, but the margin was definitely surprising.

For Trump (flips):
Pinellas, FL
Trumbull, OH
Macomb, MI (margin)
Elliott, KY (margin)
Suffolk, NY
Monroe, FL

For Clinton (flips):
Orange, CA (margin)
Cobb, GA
Gwinnett, GA
Fort Bend, TX
Whitman, WA

There are a lot of rural counties in Democratic states that flipped. I don't mention them only because I don't necessarily recall them from memory.

Gray's Harbor and Pacific in WA have to be two big surprises as well, especially the margin Trump won by

[Figueira]

Yeah, if we're counting margins, then Elliott KY definitely qualifies.

In Maine I'd say the most surprising were Androscoggin and Kennebec. I did not expect those to flip.

I think Niagara County, NY, warrants a mention, not necessarily because of the outcome, but how stark it was. This went from being a consistently polarized county that refused to ever swing to an almost 20 point Trump victory.
