Here is how the vote in rural and exurban counties looks on a map. Blue counties went Democratic; red counties are Republican. Dark red counties had Republican landslide wins, where Romney won more than 55 percent of the vote. Dark blue counties were landslide Democratic.
More than seven out of ten rural and exurban counties were landslide Republican counties.
Only a little more than 15 percent voted Democratic in 2012.
