Which State results do you find the most surprising ?

Already been mentioned, but Missouri in 1956.  

How did Ike go from a 29,599 win in 1952 to a 3,984 vote loss in 1956?  Also, there were five minor parties on the ballot in 1952, but only Eisenhower and Stevenson on the ballot in 1956.

Certainly, the farm crisis hurt Ike in '56 in the plains states, which I guess is the only plausible explanation.  He was weaker in Kansas, Nebraska, and Iowa in '56, but stronger in Illinois, Kentucky, Arkansas, Oklahoma, and Tennessee (slightly).

The Truman win in CA in 1948 was probably narrow because the popular CA Governor, Earl Warren, was Dewey's running mate.  Really, in retrospect, how did a ticket with the NY and CA governors on it not win the Presidency?

Michigan reverting to Roosevelt in 1944 after he lost it in 1940 is surprising.  The soldier vote, which was rigged for FDR, made the difference.  My Dad was in the Army in Belgium for that election.  He said that troops were instructed to vote for FDR.  He remembered it vividly as he was a Republican.
