"Show me just what Mohammed brought that was new, and there you will find things only evil and inhuman, such as his command to spread by the sword the faith he preached." - Manuel II Palelologus
Even if that is true (and I think you are in denial - the evidence is that Americans HAVE been turning their backs on conservatism) its still not very good news. If moderates are being voted out it implies a hardening of political opinion, a growth of extremism and a deepening of what is already an uncomfortable political divide in the USA.
To be more accurate, you would have to say that the moderate republicans have been wiped out because moderate democrats are flourishing.
The key phrase in the article is the direct quote:
"Its a party(GOP) that's becoming more narrow and there's really no sense of compromise."
The cultural conservative's aka cultural populist's positions are based on moral absolutes, and there is no compromising moral absolutes.
As an example of the moral absolute, James Dobson refused to endorse McCain, until McCain picked Palin.
The cultural populists were kicked out of the democrat party in the 60s and they gradually joined the GOP and eventually became the power behind the throne. It is only natural that they now want to own the GOP and implement their dominionist "heaven on earth".
The problem with that is that they don't have enough votes to nominate God, much less get him/her elected.
