In my experience AGW deniers fall into two camps:
Conservative Republicans, they will support CTs with Democratic villians, i.e. all the anti-Clinton and Obama stuff, the former smuggled cocaine and killed Vince Foster, the latter was born in Kenya, is a closet Muslim or Socialist, is coming to get "our" guns etc.
General CT kooks who believe in 9/11 etc CTs, most seem to support Ron Paul and are so much hardcore Libertarians as they are distrustful of gov't.
There is quite abit of overlap and many exceptions but what unites them all is they are unimpressed by the overwhelming rejection of their views by qualified experts. but oddly put a great deal of faith in the handful of 'dissident' experts and fake experts TV weathermen re:AGW, electrical engineers and KFC architects re:the WTC collapses etc. who tell them what they want to hear.
And there are the Bible thumping CT kooks who are especially suspicious of da Jooooz.
