God's Own Party has a demographic advantage...from an article by Phillip Longman in USA Today:

What's the difference between Seattle and Salt Lake City? There are many differences, of course, but here's one you might not know. In Seattle, there are nearly 45% more dogs than children. In Salt Lake City, there are nearly 19% more kids than dogs. This curious fact might at first seem trivial, but it reflects a much broader and little-noticed demographic trend that has deep implications for the future of global culture and politics. It's not that people in a progressive city such as Seattle are so much fonder of dogs than are people in a conservative city such as Salt Lake City. It's that progressives are so much less likely to have children. It's a pattern found throughout the world, and it augers a far more conservative future - one in which patriarchy and other traditional values make a comeback, if only by default. Childlessness and small families are increasingly the norm today among progressive secularists. As a consequence, an increasing share of all children born into the world are descended from a share of the population whose conservative values have led them to raise large families. A single child replaces one of his or her parents, but not both. Consequently, a segment of society in which single-child families are the norm will decline in population by at least 50% per generation and quite quickly disappear. In the USA, the 17.4% of baby boomer women who had one child account for a mere 9.2% of kids produced by their generation. But among children of the baby boom, nearly a quarter descend from the mere 10% of baby boomer women who had four or more kids. This dynamic helps explain the gradual drift of American culture toward religious fundamentalism and social conservatism. Among states that voted for President Bush in 2004, the average fertility rate is more than 11% higher than the rate of states for Sen. John Kerry.
