During the Reagan era , the GOP did hook up strongly with The Christian Coalition as a voting block . This was when televangelists and mega churches were started to really gain steam . They pandered to their specific wants and sort of blew in their sails by giving them more access in Washington . There are a lot of the Christian organizations churches or radio show hosts who still influence a lot of people on the GOP side . The majority of calls for a theocracy are rooted in the Dominionists who believe that they are to make a Christian world for Jesus to return to and rule over . vs the more common idea of a Rapture event . Probably one of the best known Dominionist organizations is Morningstar Ministries and their pastor has given sermons on life in the theocracy hint , not much better than life in Islam . They believe in a Seven Mountains prophesy where Christians are to take the head of the seven mountains . One of those mountains is politics . They also believe in praying away evil spirits from people and locations . They often talk about doing battle with the enemy the documentary Jesus Camp was about a childrens camp from this belief system . Bush had a lose association with these people as POTUS , but he wasn ' t really bought into it . Sara Palin has very strong ties to it and when she talks you can hear phrases that are common to those groups .
