There's no reason Protestant Fundamentalism and political Conservatism need be connected, but they are.

I'm well aware there are born-again Christian Liberals and atheist Conservatives. Think Jimmy Carter and Ayn Rand. But these are outliers, the exceptions that make up the rule.

The very high correlation between Christian Fundamentalists and Political Conservatives, at least in the USA, is no accident. The two have fed off each other and to a very great extent depend on one another. There isn't the slightest doubt in my mind that this connection is deliberate and carefully fashioned, it is not a coincidence, it is causal, it has been planned, crafted, implemented and nurtured. How and why these two pestilences always seem to occur together may be a matter of debate, but the fact that they are reliant and dependent on each other in today's American political landscape is not.
