First, and most importantly, the consistently loyal Democratic counties were the large
counties with an average 2010 population of 415,933, while the consistently loyal Republican
counties, that is, those which voted for both McCain in 2008 and Romney in 2012 were the
smaller counties with an average population of only 24,653 people. The swing or more
marginal counties which voted for Obama in 2008 and for Romney in 2012 fit neatly in-between
with an average population of 82,111.
As expected the Obama counties in 2008 and 2010 are much more diverse racially and
ethnically than the Romney and McCain counties are. That is, those consistently loyal
Democratic counties which voted for Obama in both 2012 and 2008 were 85.8 percent white,
9.4 percent black, and 8.9 percent Hispanic. Those which were consistently Republican, voting
for both John McCain and Mitt Romney were also much more homogeneous with 93.7 percent
white, 2.9 percent black, and only 2.2 percent Hispanic. Those which split between voting for
Obama in 2008 but voting for Romney in 2012 again fell neatly in between. They were 93.2
percent white, 6.6 percent black, and 5.8 percent Hispanic. In the social sciences one rarely
encounters empirical data where the pattern is clearer than that found in Table 3.
These aggregate level demographic results were certainly consonant with the national picture
and the analysis provided from the exit poll data provided by the national news organizations
(See for example: The Economist , November 10, 2012, 27-29; The Washington Post,
http;/www.washingtonpost.com/wp-srv/special/politics/2012-exit-polls/accessed, January 18,
2013). Those post-mortems stressed the racial and ethnic diversity of the Obama coalition and
how much his victory depended on the votes of those who in the past typically turned out at
lower rates and how well he ran among the black and brown voters while losing white voters by
a substantial margin. The turnout rate and the much vaunted Obama ground game were given
widespread credit for mobilizing the vote at historic levels among these populations in 2008
and then matching and in some states exceeding those levels again in 2012.
Another set of important demographic and socio-economic variables are those provided by
income, housing stock, and poverty rate data. These too are provided for the 2012 and 2008
results in Table 3. It is quite clear here that the median home value is highest in the
consistently Obama counties, second highest in the counties Obama carried only in 2008, and
lowest in the Romney counties. Likewise, median household income and per capita income
exhibited the same pattern. The affluent counties were also the Obama Counties, and the
next most affluent counties were the swing counties. The least prosperous counties, as
measured by median home value, per capita income and median household income, were also
the most loyal Republican Counties. (See Appendix B, C, and D for the data on each county).
The only minor variation on this overall pattern was in the percent below the poverty level
which was highest (at 14.1 percent) in the 2008 to 2012 swing counties, then next highest in the
