Not likely. KY-5 is a district that is historically Republican, with very, very few black residents at all. These sort of districts are NOT the kind of districts that would produce a Chris McDaniel, let alone a straight up white nationalist.
Rogers is NOT a movement conservative; he's close to an old-time Mountain Republican, and his district is likely to produce such a Republican as his successor.
I mean in the 90s it was polarized af. The eastern portion was very democrat but the the sw portion was just as republican
That is because the 1990's and subsequent KY-05 included large portions of the old KY-07, which had been held by Carl Perkins. The Western portion of the district though is a historical bastion of Mountain Republicanism.
Also Mountain Republicanism isn't completely out of touch with Trumpism.
