\description{
A data set for 1980 Presidential election results covering 3,107 US counties using geographical coordinates. In addition, three spatial neighbour objects, \code{k4} not using Great Circle distances, \code{dll} using Great Circle distances, and \code{e80_queen} of Queen contiguities for equivalent County polygons taken from file \code{co1980p020.tar.gz} on the USGS National Atlas site, and a spatial weights object imported from \code{elect.ford} - a 4-nearest neighbour non-GC row-standardised object, but with coercion to symmetry.
