Two facts: Fergus Falls is the county seat of Otter Tail County, one of 4 Minnesota counties that voted for Barry Goldwater in 1964

Minnesota Town Defamed by German Reporter Is Ready to Forgive.  (The New York Times, 12/27/2018)

Unlike other American counties that voted for Mr. Trump, there was not a wild political swing in Fergus Falls, making it a strange place for Mr. Relotius to choose to profile. Otter Tail County had also supported Mitt Romney and John McCain. And well-trod story lines about factory closures and population decline, often cited in accounts of Mr. Trump’s success, did not apply in Fergus Falls, where the downtown is bustling and the population is steady.

Trump's margin of victory in Otter Tail County, 35.7 percentage points, is the largest since 1952, when Eisenhower beat Stevenson by 50.4 percentage points.  (In 1964, Barry Goldwater received 51.3% of the vote to LBJ's 48.6%.   Minnesota has 87 counties.)
