In the US I'll guess CA-25 and ME-02.
CA-25 is reactionary in the parochial class grievances and cultural monocle-popping typical of anti-urbanist Sun Belt suburbia (Goldwater cleaned up in many such parts of outer LA, not just OC and SD). ME-02 is historically a slice of Yankee New England sprinkled with French-Canadians, parochial in opposite ways and quite fond of its types in Congress both Dem and GOP, including many who would later hold statewide office, but now mainly totalized into typical American polarizations with your post-industrial meth havens and resort country and hippie college towns and Native reservations amidst unwashed "WWC" masses for those of your ilk to navel-gaze about producing no real total political character.
The sui generis liquid-postmodern pathologies of American politics make it difficult to analyze districts in aggregate through such a lens. Perhaps I should call MD-06 the most right-wing Dem seat on account of it smashing together inner DC managerial gentrifiers, suburban SALT/"muh property value" concern trolls, post-extractive malaise in Western Maryland, and German Yankees-turned-Q-nuts, all under the aegis of a liquor store owner Congressman who carpetbagged there after failing to buy a primary in what's now Raskin's seat at great personal expense. MN-08 most left-wing GOP seat? Choose your own narrative.
