Who was the most "electable" candidate for both parties, by year?

[Mr. Smith]

Here's my take:

1912: Wilson (D) vs Teddy without the split
1916: Hearst (D) vs Johnson (R)
1920: Johnson (R) vs Mc Adoo (D) [That said Cox was actually perfectly fine,it's just that Harding never went against him,he went against Wilson who was unpopular.]
1924: Coolidge (R) vs  Al Smith (D) [who should've then put Mc Adoo on the Veep spot]
1928: Wouldn't change anything
1932: Wouldn't change anything
1936: No change
1940: No change
1944: No change
1948: Truman (D) vs Warren (R)
1952: Eisenhower (R) vs Kefauver (D)
1956: Same as '52
1960: No change
1964: Johnson (D) vs Rockefeller (R)
1968: R.F. Kennedy (D) vs Romney (R)
1972: Nixon (R) vs  Muskie (D)
1976: Jackson (D) vs Reagan (R)
1980: T. Kennedy (D) vs Bush (R)
1984: Reagan (R) vs Hart (D)
1988: Dole (R) vs  Biden (D)
1992: Buchanan (R) vs Brown (D)

1996: Clinton (D) vs Wilson (R) [Pete Wilson was considered moderate and he could tout being from the same state as Reagan,and had an immigration stance that'd excite the base]

2000: Mc Cain (R) vs Gore (D) [Once again,Mc Cain also the moderate,but approachable thing going for him to counter out Gore and the know-how sort of persona exuded]

2004: Bush (Dubya) (R) vs Edwards (D) [Bush was somehow popular, he was still hailed for his efforts. But Edwards could've taken on some of the South and Ohio with his appeal to the poor,he was still rising then]

2008: Clinton (D) vs Mc Cain (R) [Obama had the luck of a good campaign and the selection of Palin by Mc Cain,otherwise he appears like a flip-flop and a bit celebrity like vs Clinton's experience and moderate stances. You can bet she would've won Missouri,Arkansas, Georgia, and Montana with only Indiana lost. And as for any other GOP,they all appear too conservative and Bush-like]

2012: No change [People actually believe the crazy things about the deficit,so any remotely liberal replacement would be shot-down despite Obama not being in a good place. And all of Romney's opponents were simply wingnuts who'd alienate everywhere except the middle states and the Deep South]
