1984 it was Reagan 525-13, Nixon in 1972 came close 520-17. Nixon lost Massachusetts and D.C.

You forgot the mountain states, Idaho, Montana, North and South Dakota, Wyoming, Alaska. The fact that Biden now has a two point lead in Georgia and is tied with Trump in Texas, to use an old G.H.W. Bush phrase, Trump is in deep doo doo.
