Check out this chart over at Zillow.
Stan Humphries, Zillow’s vice-president of data and analytics, explains:
According to Zillow’s Zindex (median Zestimate or the middle estimated home value), the Red states (pro-Bush) have substantially lower home values than do Blue states (pro-Kerry).
Red states had a Zindex of $190,323 vs. a Zindex of $323,952 for the
Blue states as of the first quarter of 2007. … In other words, while Red states were on the winning side of the election, the Blue states are on the winning side in terms of real
estate values, and by a substantial amount. … The correlation between the Zindex and Bush’s
share of the popular vote is -58%, indicating that the two measures are
fairly inversely related.
