Aren’t places like Centre and Dauphin in PA actually trending D? And some of the other <60 real Counties out in the plains should probably be a darker red. St. Louis County, MN and Rock Island IL don’t look like they’re going anywhere either
Other than that, this seems believable.
I remember reading something a long time ago that said that rural areas based on recreation voted more Democratic than rural areas based on farming
(and also other industry). I wonder if that could be at play in some of these areas. Although only one of those is near water afaik.
