The New York Times has a slideshow of various maps showing how the electoral results break down. The first map is notated “Only 22 percent of American counties voted more Republican than they did in 2004.”
This one shows that 78 percent of American counties voted more Democratic than they did in 2004.
I thought it was hyperbole when I read some pundits saying that the Republican party was on its way to becoming a regional, not a national, force in politics. But in this cycle at least, it seems it’s advantage: Democrats. We’ll see how we’re doing in about 4 years.
