There was an interesting article rolling around the internet that I can’t find right now, that talked about Presidents who were elected “in sync” with the prevailing political winds, and Presidents who were elected “contrary” to those winds. Additionally it identified the “transitional” Presidents and whether someone was a transitional President or a contrarian.
Okay so, generally this theory says that basically from FDR through Johnson, you had this prevailing wind of government getting involved in the economy, creating social welfare etc. A single contrarian President during that period would have been Eisenhower, explained by the fact that he was basically a Washingtonesque figure of massive personal popularity such that he could easily be elected despite being a Republican in a heavily Democratic-leaning time.
With Nixon’s election in 1968, you then either have a transitional President or another contrarian. This theory argues Nixon was transitional. Evidence is the wide support for many of Nixon’s issues in both elections. Carter is seen as a contrarian President elected primarily because of personal malfeasance on Nixon’s behalf and Ford attaching his name to the mud by pardoning Nixon, a deeply unpopular move (Ford still almost won reelection–Ohio was won by carter by under 0.5% which would have given Ford 265 EVs, and then a few other states were very close that could have pushed him over, so Ford came close to holding on in an electoral college victory.) The reason Carter is seen as contrarian is there is a good explanation for his election unrelated to a shifting political wind, but instead related to a specific scandal. The massively supported election of Reagan and Bush for the next 12 years was an indication of the continuing rightward political wind and thus Carter’s Presidency is more easily seen as a contrarian election.
The theory then basically says Clinton is part of that same movement, because Clinton was extremely moderate, he adopted traditional Republican ideas at many points and did not appear in most ways to be changing the prevailing wind. This theory then speculates that Bush himself was the last President in this rightward movement, and that Obama is the transitional President representing a new direction.
While I don’t totally buy into all of these conclusions, I do think there is a core thing to note. The circumstances of an individual election can lead to someone being elected from a party that is long out of favor and/or not particularly aligned with the prevailing political winds. Carter won because of a massive scandal, Clinton won because he grabbed hold of the center as tight as he could, Eisenhower won through massive personal popularity.
So such a thing is possible and could lead to a GOP President sooner than might be suspected. For example Joe Biden is a risky nominee, he’ll be 74 years old, Hillary Clinton will be almost 70. What if one of them is nominated and they drop dead during the campaign or have a heart attack or get cancer? I have serious concerns about any 74 year old person’s long term health prospects, and it’s impossible to say what a strong GOP candidate in 2016 might do if the Democrats flag bearer suffers some medical problem mid-election. Or there could be a Clintonesque Republican, whose massive personal popularity gets him through the primaries despite being out of sync with the party, who has wide appeal and wins. I don’t know of any Republicans who fit that mold at all right now, but I didn’t know who Bill Clinton was until 1992 either. (Chris Christie might be the closest, but I think he’s too grotesquely obese for national politics, and too brash and gaffe prone and far too Jersey, but a guy who is a Republican and is widely popular and willing to swing left is the concept here.)
