If the New Republican Party has a philosophy it is that of Ayn Rand (Takes and Makers, Oh my!) which is somewhat shocking. The reason this is so is that the Republican Party is the party of rich people and corporations. They have only been able to draw a sizeable number of ordinary Americans along with them by appealing to baser instincts: namely that black and brown people (unworthy by stint of coloration) are robbing them of their tax monies through welfare and government subsidies, etc. Plus, illegal brown people are stealing their jobs!
That corporate welfare (to the tune of at least $6000 per family) far outweighs anything done for the poor, be they black, brown, purple or white and that very few Americans are racing to take over the jobs done by illegals (day labor, picking agricultural fields, etc.) apparently escapes these folks, possibly because such data conflict with their racism. In any case, a large number of these ordinary conservative Americans turn out to be Evangelical Christians (aka Conservative Christians, aka Fundamentalist Christians, there seems to be no good definition of this group), which creates the pause with the Republican ideological link to Ayn Rand.
You see, Ayn Rand was an atheist. Her philosophy is steeped in secularism, so following her philosophy identifies the Radical Republican Right (aka the Tea Party) as being . . . wait for it . . . secular atheists.
I wonder if anyone has told that to the Evangelicals? Why I think they would want to split off on form their own party.
