The July 14 issue of Time Magazine discusses Catholic voters in the 2008 U.S. Election. The map is striking in one major way - the south looks devoid of any concentration of voters. As a Catholic living in Huntsville Alabama, I can tell you for a fact that we are in the minority. However, look at the map again and ask yourself that if you didn't know the title of the article whether you could indeed determine what the map was depicting. So, here's this huge void from Virginia to North Florida and from the east coast to middle Oklahoma. It looks more like a maps of some great flood in the southeast that had wiped out the population.
The distribution of voters is not obvious - a high concentration in the northeast and in the southwest but I'm not sure I would have guessed the map without the title. The bottom line as of this date is that it is a statistical "dead heat" between McCain and Obama.
