Is There a Christian Nationalism in America?

People have been talking about this sort of drift towards Republicans among Black voters Hispanic voters, but particularly among black voters I wonder if do you think it's because black voters are inherently conservative that they stick with voting Democrat. You know in the 1920s and 30s black voters went almost entirely Republican black people voted Republican fully. Slowly over the course of maybe two decades shifted not all at once but sort of one election at a time. So by the late 60s black Americans were a solidly Democrat party, but again early 20th century black voters were as Republican as We are Democrat now so things can change over time.
