Here is the US apportioned based on Anderson 1980 voters
(RI 7, CT 15)
As you can see, Yankees as we knew: moderate old school Eisenhower Republicans, the descendants of the pre-FDR Republicans that brought us figures like Calvin Coolidge. These are the same Republicans that gave us Lincoln Chafee in RI. They have been slowly pushed out of the GOP starting with Goldwater, then Reagan, then Dubya, and now with Trump in office they were the New Hampshire Democratic primary voters that went with Buttigieg.
