The proportion rises to 68% among those who would like to see former Gov. Mike Huckabee become president.
The survey does not ask any further questions about the respondents' understanding of the Constitution or of Christianity. My guess is that this position does not rest on a deep analysis of either.
Instead, this is the characteristic conservative loyalty to what they imagine to be "traditional" as being sacred.
The irony, of course, is that what is actually traditional in the United States is that we definitely do not allow an established religion.
Moreover, I am sure that that majority agreement among Republicans on establishing "Christianity" would disintegrate as soon as they got down to any specifics of which practices of Christianity they have in mind.
