I’d just like to point out — not for the first time here — that there’s a difference between the southern US and everywhere else. While you can find biscuits and gravy in lots of restaurants, it’s a SOUTHERN thing originally, and I wouldn’t be eating it in any state that didn’t go heavily for Trump. Same with hush puppies, cornbread, a mint julep, or pecan pie.
For a nation that makes fun of gap-toothed, six-fingered yokels that live in towns a mere 15 minute train ride away from the erudite urbanites among you, I find it funny that anyone would think a nation twenty times your size in square miles would think some culinary trend was a nationwide thing. Okay, okay . . . McDonald’s, sure. :)
