Survey indicates that a lot of Americans identify themselves as or support "Christian nationalists."
https://www.washingtonpost.com/opinions/2023/02/09/prri-poll-christian-nationalism/“Christian nationalism is a new term for a worldview that has been with us since the founding of our country — the idea that America is destined to be a promised land for European Christians,” PRRI president and founder Robert P. Jones explained in a news release on the survey of more than 6,000 Americans. “While most Americans today embrace pluralism and reject this anti-democratic claim, majorities of white evangelical Protestants and Republicans remain animated by this vision of a white Christian America.”
The poll used the following beliefs to gauge how deeply respondents embraced Christian nationalism:
PRRI found that 10 percent (“adherents”) of American adults believe in these ideas overwhelmingly or completely; 19 percent agree but not completely (“sympathizers”); 39 percent disagree (“skeptics”) but not completely; and 29 percent disagree completely (“rejecters”).“The U.S. government should declare America a Christian nation.”
“U.S. laws should be based on Christian values.”
“If the U.S. moves away from our Christian foundations, we will not have a country anymore.”
“Being Christian is an important part of being truly American.”
“God has called Christians to exercise dominion over all areas of American society.”
