"Who are these people and what motivates them? To answer, one must leave the field of conventional political theory and enter the realm of psychopathology. Three books may serve as field guides to the farther shores of American politics and the netherworld of the true believer.
Most estimates calculate the percentage of Republican voters who are religious fundamentalists at around 40 percent; in some key political contests, such as the Iowa caucuses, the percentage is closer to 60. Because of their social cohesion, ease of political mobilization and high election turnout, fundamentalists have political weight even beyond their raw numbers. An understanding of their leaders, infrastructure and political goals is warranted. Max Blumenthal has done the work in his book "Republican Gomorrah: Inside the Movement that Shattered the Party." Blumenthal investigates politicized fundamentalism and provides capsule bios of such movement luminaries as James Dobson, Tony Perkins, John Hagee and Ted Haggard.
The reader will conclude that these authority figures and the flocks they command are driven by a binary, Manichean vision of life and a hunger for conflict. Their minds appear to have no more give and take than that of a terrier staring down a rat hole.
Blumenthal examines the childhoods of these religious-right celebrities and reveals a significant quotient of physical and mental abuse suffered at the hands of parents. His analysis of the obvious sadomasochistic element in Mel Gibson's films - so lionized by the right wing - is enough to give one the creeps.
