Nixon, the incumbent VP, inherits the President from a popular President in 1960 -- NOT!
Eisenhower 1956, Nixon 1960 blue (Alaska* went for Nixon in 1960 -- light blue)
Eisenhower 1956, Kennedy 1960 white
Stevenson 1956, Kennedy 1960 red (Hawaii* went for Kennedy in 1960 -- pink)
Stevenson 1956, "uncommitted" 1960 green
No state went from Stevenson to Nixon in 1960.
I would guess that both Alaska* and Hawaii* would have gone for Ike had they voted in 1956.
Gore, the incumbent VP, inherits the President from a popular President in 2000 -- NOT!
Dole and Dubya -- blue
Clinton and Dubya -- green (Florida disputed for a month... thus the light shade)
Clinton and Gore -- red
No state went from Dole to Gore.
Gore lost fully eleven states that Clinton had won four years earlier... and any one of them could have ensured that the Great Disaster would have not been President.
California was won by Gore...by 11 points, and hasn't voted GOP since '88.
