As in, the Republican wins almost every state. But the Democrat wins their home state by a hair, and carries a handful of solidly Republican states (some in a landslide).
The closest we've gotten to this is 1988, with Dukakis underperforming in his home state of Massachusetts (winning by just 8 ) but dominating in Iowa by over 10 and nearly winning Vermont, two very GOP states back then. He also managed to solidify a number of states like Oregon, Washington and New York in the D column as well as narrow into single digits what used to be double digit GOP margins in California, Colorado and New Mexico, much like Goldwater did with the Deep South.
1984 would have easily qualified if the farm crisis had hit full swing earlier.
