Huckabee would like to replace US Democracy with a Christian Caliphate.
Huckabee says that we should only follow US laws that are "right". Huckabee's definition of right is HIS interpretation of the Christian religion and the Bible.
I am a Christian and I disagree with Huckabee what is right on many issues.
No religions member agree on what is "right".
Thus you form a Caliphate and have one person tell everyone what is "right" as determined by God.
You do realize that "Christian Caliphate" is a contradiction, right?
A Caliphate is a structure of governance in the Muslim religion.
My point is the structure could be applied to the Christian or any other religion. The structure is the doctrine of the religion is the ultimate "constitution of the government".
Because every religion has differences, the government is led by one religious leader who has final say on any disagreement of how to interpret the religious doctrine.
