I wrote here here that the red/blue map was not redrawn; it was more of a national partisan swing.
In comment #39 to that entry, Scott de B. wrote: “How else would you define ‘redrawing the red/blue map’ other than ‘a nationwide partisan swing’? By your definition, Reagan didn’t redraw the national map, but if Mondale’s lone state in 1984 had been Alabama instead of Minnesota, he would have.”
My first response is that, yes, Obama’s national swing was important, but it didn’t much change the relative positions of the states. Let’s see what happened in 1980/1984:
and in 1976/1980 (newly added):
These changes were indeed less uniform in their swings as compared to 2004/2008.On his blog, Steve Sailer wrote: “If you drew up the equivalent graph for the 1952 and 1956, which featured Eisenhower and Stevenson running both times, it would look more like a random scatterplot. On a state-by-state basis, the political environment was a lot more dynamic in the 1950s than today.”
OK, what did the 1950s look like?
Not exactly a random scatterplot but, again, more variation than we saw in 2000/2004 and 2004/2008. Actually, the variation from 1952 to 1956 and from 1980 to 1984 is more comparable to the variation in two recent elections, say from 2000 to 2008:
P.S. Above graphs fixed; thanks to commenters for pointing out the errors.
