Here's my guesses (since I obtained these by modifying the actual maps, it is possible the maps look more like the actual results than they should).
1960: Nixon 476 EV, Kennedy 53 EV, Unpledged 8
1964: I wasn't able to post a map but Johnson 401, Goldwater 137, with Goldwater adding IN, NC, TN, AR, NE, KS, ID.
2012: Romney picks up OH, VA, FL, still loses 272-266.
Here's my guess as to nationwide vote:
1960: 35/65
1964: 54/46
1968: 32/51/17
1972: 26/72
1976: 40/58
1980: 30/63/6
1984: 28/71
1988: 35/64
1992: 35/44/20
1996: 44/45/9
2000: 44/53
2004: 45/54
2008: 49/50
2012: 47/51
