2012 Pres statistical oddities

[homelycooking]

I assume Dodge was a one vote swing?

Swing isn't measured in terms of votes. The R-D margin remained almost exactly the same from 2008 to 2012, though the percentages of both declined equally (slightly better 3rd party performance in 2012) and the actual number of votes cast for both declined as well (lower voter turnout in 2012).
