When I hear "landslide," I think of FDR in 1932 and 1936, Eisenhower in 1952 and 1956, LBJ in 1964, Nixon in 1972, and Reagan in 1980 and 1984. The popular definition of a landslide seems to be around 350 EVs however, as most people consider Bush 88 and Clinton 92 and 96 to have been landslides.
Reagan in 1980? Lol. Certainly not landslide territory (and only barely wider than 88 and 96.)
Unless we take "landslide" back to its original meaning and take it to indicate *movement* (whether compared to the previous election or to expectations during the campaign.) In which case, 1992 certainly qualifies but 1936 doesn't... and 1980 and 1984 are of similar magnitude...
So yeah, whatever. This election won't be describable as one unless all the closeish Rep states flip, and won't be
honestly describable as one, full stop.
