If you want to understand the Vast Right Wing Conspiracy-here's a good explanation.

A commentator at the The Reality Based Community blog explains how the GOP is structured and intimates the differet interests at play.

Here's a taste:

The VWRC is a conspiracy, composed of several factions, most of whom hate each others' guts. The economic predators sneer at the Taliban, as their lawful prey. The Taliban correctly view the predators as godless ghouls. The ultranationalists correctly view the predators as having no loyalty to the US. The neocons think that the whole pack is ni kultyurni. The ultranationalists and predators correctly view the neocons as mutant Trotskyites, useful only for propaganda. (Nobody trusts the neocons or libertarians; they are too tainted by Enlightenment ideas.)

It gets better. Reader Joe explains why a lot of the Conservative big wigs don't like McCain, but also why they may never fall in line behind him.

This is highly recommended reading.
